Rumor has it that when computers behave the strangest way, the only sensible solution is replacement, especially when it runs terribly slow. However, looking on the bright side-certainly you would start doing so-after reading a couple of intelligible articles in the internet (including this article, of course) you will find out that you do not actually have to replace anything. All you have to do is to make a few checkups, perform a little fix on the disk, and restart your system to transform it into an incredibly fast machine as if it was brand new. You can definitely fix PC speed, and you can do it with these steps, for free!
First, you need to be familiar with the simple computer terms which you will be working with from now on. There is the Windows Registry, which contains all the essential system files that your computer needs in order to keep processes and programs in an order that can be comprehended by your PC. The Windows Registry is also the most vulnerable area of your computer. This is because it is the commonplace for viruses and worms, particularly due to the fact that these threats would like to multiply and destroy everything as quick as possible, and your Windows Registry, being one of the weakest spots in your PC, can make that happen in a matter of days. To fix PC speed related to registry problems, the best solution is to install a registry protection software that will eliminate any of these registry threats. Of course, you would have to regularly scan and update the software in order to ensure maximum protection against these virus attacks that could make your files and programs unusable.
Next, you should also be well-acquainted with the terms Disk Defragmenter, Recycle Bin, Windows Configuration Utilities and Temporary Internet Files in order to fix PC speed problems. If you still do not know these terms, you can type in these keywords in your Microsoft Help Topics and read further on their operations. As an overview, the Disk Defragmenter is a Windows tool that lets you defrag your files in order to reorganize fragmented data in your system. The primary purpose of data defragging is to keep your hard disk compact, which means that your system will find it easy to fetch the necessary processes required by certain programs to run. Consequently, the cache of your computer files and processes would be out of order if your have a fragmented disk, and the time experienced in waiting for the cache to load the applications that you need is a clear indicator of the reduced speed of your computer. In order to fix PC speed, we need to defrag our hard disks as often as possible, especially when the user frequently installs, deletes, or copies files and programs from the internet or other external devices to his PC. Keep in mind that a more organized computer system is all you need to fix PC speed problems, and you can maintain that PC performance by keeping your registry protected from online threats.

Using The ClipBoard In A Macro By Threading
How do I access the Clipboard in a Macro? Just using GetData and SetDataObject does not work. This article will show you how.
You would think that the Clipboard object would work the same in a Macro as it does in an application. That would not be correct. If you simply try to use the clipboard in a Macro, your code will fail due to the way that macros work at the behest of the IDE. The error you will get is the old "object not set to an instance of an object" message. Therefore, to make a long story short, you need to create a separate thread to access the Clipboard.
First, make sure that the following Imports are present in the Macro Module that you will use for your sample macro to access the Clipboard.
Imports System.Threading
Imports System.Windows.Forms
Next, place the following module level variable in the module.
Private clipString As String = String.Empty
Next, create a method in the Module to retrieve the contents of the Clipboard as follows:
Public Sub GetClipboard()
Dim cbThread As Threading.Thread = _
New Threading.Thread(AddressOf GetClipboardText)
With cbThread
.ApartmentState = ApartmentState.STA
.IsBackground = True
.Start()
' Wait for clipboard action
.Join()
End With
cbThread = Nothing
' at this point, the contents of the Clipboard will be in the
' module level variable clipString
End Sub
Finally, create a method that will place text on the Clipboard as shown below:
Public Sub SetClipboard(ByVal text As String)
' put the results back on the clipboard
Dim ClipBoardThread As Threading.Thread = _
New Threading.Thread(AddressOf PutTextOnClipboard)
With ClipBoardThread
.ApartmentState = ApartmentState.STA
.IsBackground = True
.Start()
' Wait for clipboard action
.Join()
End With
ClipBoardThread = Nothing
End Sub
The following methods are called by the two threads created in the code shown above.
Sub GetClipboardText()
clipString = _
Clipboard.GetDataObject() _
.GetData(System.Windows.Forms.DataFormats.StringFormat)
End Sub
Sub PutTextOnClipboard()
Clipboard.SetDataObject(clipString, True)
End Sub

.ApartmentState = ApartmentState.STA
.IsBackground = True
.Start()
' Wait for clipboard action
.Join()
End With
cbThread = Nothing

' module level variable clipString
End Sub
Finally, create a method that will place text on the Clipboard as shown below:
Public Sub SetClipboard(ByVal text As String)

' Wait for clipboard action

End With

Sub GetClipboardText()
clipString = _
Clipboard.GetDataObject() _
.GetData(System.Windows.Forms.DataFormats.StringFormat)
End Sub
Sub PutTextOnClipboard()
Clipboard.SetDataObject(clipString, True)

Go Paperless - Invest in Electronic Medical Records EMR Software
In our heterogeneous healthcare system, we have endless number of medical professionals, all practicing differently, using different billing systems, having different levels of computer proficiency and workflows. Sadly, over 50% of practitioners still follow the old-fashioned medical practice management systems, dealing with tons of nerve-wrecking paperwork on daily basis.
Today, the medical software market is brimming with emr experts pursuing a wide range of highly sophisticated and viable emr applications that help doctors in managing their patient information, practice profile and financial records with utmost convenience and security.
Like any other product, EMR software programs are two kinds:-
- Client or Server-based EMR system and
- ASP or Web-based EMR system.
1. Server/Client based EMR system
This is the most popular electronic medical records software wherein the program is hosted on the vendor's site. Client/server-based personal medical software may also be hosted on the in-house medical billing system.
Pros
- Faster overall operational speed.
- No dependency on internet connection.
- Better integration with imaging devices (scanners, printers) and on-site resources.
- Control over your own data.
Cons
- Higher upfront cost of ownership as a server and software must be purchased upfront.
- Online backup must be purchased as add-on 3rd party software.
- Remote access to EMR is limited in functionality and is more complex.
- Manual product updates are usually required (not in all cases).
2. ASP or Web-based EMR system
A web-based medical office billing software runs right off the web server. For this type, all you need is an internet connection.
Pros
- System is maintained by IT professionals remotely, reducing the cost of maintenance.
- Accessible anywhere in the world from any computer with an internet connection.
- Online backup service.
- Low initial cost of ownership.
Cons
- Dependant on internet connection.
- Risk of data being inaccessible in the event company goes bankrupt. You don't control your data.
- Risk of company not performing routine maintenance (backup, updates, performance enhancements) as promised.
- If your internet connection goes down you cannot use your system.
Both upfront and ongoing costs have been critical factors in the lagging EMR/EHR adoption rate. But best things in life come with a price. However, one time investment in reliable medical practice management software seems quiet miniscule against the lifetime advantage of running your clinic much effortlessly and efficiently.
Electronic Medical Record software solutions are still in their early adoption phase by private practice physicians. With noticeable migration at this point, it is difficult to judge which is better - Web or Server based emr software? Doing some research can assist doctors in taking informed decisions on what is or isn't important to their practice.
Houston Medical's server/client based medical software has been designed to meet all the Financial, Claiming, Administrative, and Clinical requirements of today's healthcare professionals. From a private medical practice to hospitals, the physician practice management program covers a wide range of functions and options used in medical billing and accounts payable management. This one-size-fits-all system is user-defined to suit every practice type, accommodate every level of patient information and process complex financial data.
Houston VIP has proved to be an invaluable tool for almost every practice type operating in New Zealand and Australia. To learn more about the medical software company and its EMR/EHR solutions, you may visit www.houstonmedical.net

The Best Registry Repair Application
There may be a lot of registry repair tools available, but there are only a few which are able to clean out your PC and make it run faster & smoother. Unfortunately, many of the cleaners on the Internet are designed by amateur coders who do not have the skills or resources to make their software as effective or safe as possible... leading many people to actually cause damage to their systems after using one of these "dud" cleaners.

Each time you use your PC, it has to read many 100's of registry settings in order to help it recall a vast array of data. But as so many of these settings are open at once, many computers get confused and save a lot of these files in the wrong way, causing them to become corrupt and damaged. Over time, Windows systems collect 100's of damaged registry settings, which all work to slow your PC down and make it run extremely slowly. To fix this, registry repair tools scan through your PC and fix the damaged settings that are inside it.
The best registry repair tool is called "Frontline Registry Cleaner", as its able to consistently remove the largest number of errors from the typical Windows system. This cleaner is highly popular thanks to the way it's able to cure many common errors on the typical Windows computer.

Non-Linear Video Editing
Once you pick up how video editing works, you will have a great deal of fun in finalizing your video clips on the computer. Videotape editing these days is a lot less expensive when equated with editing years ago. You can do it rapidly by utilizing the proper video editing program. Even so, the studying curve is somewhat steep and many individuals stop because they are easily intimidated by the program. If you're determined to study how video editing works, you are able to manage any tasks in spite of how challenging it is.
What you need to do is pick up the fundamentals and at that time, you may have much fun in editing your film footage. When you open any video editing program, you will see an interface with so many windows. As a matter of fact, among all computer programs, video editing is the most complex. You can readily get overwhelmed with the numerous window panes that pop on the screen once you open the program.
If you've tried using WMM (Windows Movie Maker), then you already have an idea of what a universal interface appears like. Most programs follow the same on-screen layout. WMM is simpler to utilize than other complex programs because you will first of all see four separate window panes on the screen. Other windows can be opened one at a time so you won't be confused in employing them. Each of the windows has its own function and once you understand the different functions, you can work without any difficulty. You can likewise camouflage other window panes while you're working. Virtually all editing programs have 8-20 window panes. These window panes confuse new users in particular when they hardly know anything about video editing.
When you open WMM or any other basic video editing program, you will see that the three window panes are placed on the top-half section and the bottom half incorporates a huge window. These four window panes are the timeline, task pane (on the upper left), collections (middle), and output (on the far right). The bottom window is the timeline or the turquoise section.
The timeline is one of the most important windows in the program. You can build your movie or video in this window pane and it will serve as its visual icon. A squiggly line or waveform icon can be seen on the screen as well as a running time on top. In the WMM timeline, one line is for the common video, titles, and video transitions or effects; for audio, there are two lines. At the left side of the screen, you will see the labels and black furrows separate them horizontally. Complex programs ordinarily have additional lines for audio and video. If you want to create simple film footage, WMM and other free software programs may be enough.
On the chore pane, the different jobs are shown and included in the list is the 'edit movie'. Links are also found in the screen which leads to other functions and one of these links teaches you how to edit film footage. You can hide/show this window on the menu at the top portion. The collections window holds all the media from your projects. You can watch the edited video/movie in the output window pane.
In videotape editing, you will be working on these four window panes the majority of the occasion. You can study how these four windows work and then learn more about the other window panes.

Free Registry Cleaner Reviews
One system component which is mostly responsible for the errors and crashes a computer may encounter is the windows registry. When a pc starts to act strange most of us will search the internet for free registry cleaner tools which are obviously the quick solution to restoring your computer back to a usable state. You will find that most people who have computers don't have a clue as to what this system component is and why it can become the centre of common problems and with this in mind I would like to speak briefly about it.
The registry is such an important component of your operating system because its primary function is the storage of all information related to the hardware and software configurations that reside on your pc. Over time the average pc will become the victim of continuous software and hardware changes which will cause the registry information to change and consequently affect the performance of your pc. You see, when you change software, make changes to settings in control panel, change file associations and edit system user profiles you will cause some entries in your registry to become obsolete while other new ones will be added. Since windows has to constantly refer to this system component to process information related to application and task execution you can now understand why your pc will become less functional if it is erroneous. Using a free registry cleaner tool is the right way to go about diagnosing these errors and keeping you pc error free.
Some of the most common errors symptoms include missing application files, deleted shortcuts, less functionality, error messages and system crashes. Continuous maintenance with a free registry cleaner program is the key to ensuring that your pc is kept in good health.

Online Computer Support - A Must For Everyone
With the increasing reach of computers into every sphere of our lives, it is but obvious that there needs to be a backup of sorts to handle issues related to the same, which are obviously bound to arise. This is where professional online computer support comes into the picture.
Generally, people call a computer technician to take care of any issues that arise during normal working with the PC. These might be slow processing, virus attack, hard disk crash, etc. There are also a multitude of hardware problems that not everyone can fully understand, and thus it is required for everyone to have professional help. However, calling a technician often leads to quite a few pain points.
The first issue that you might have with a technician is obviously whether he would always be available or not. This is particularly a major point of concern for people living in remote areas, or in case the problem is such that delay would only make it worse. Since there might be many more households that would require his services, there may be days when you would have to wait for hours and hours together to get him to first have a look at your problem.
The next problem which calls your attention is that your technician might not always be qualified to handle all kinds of problems. This basically means that technology is changing everyday, and your local technician might not be skilled or updated enough to handle all kinds of problems. This might also lead to him further complicating the problem!
The third point of concern could be the fact that he could charge you exorbitantly for services and hardware, marking his own commission in the latter. Since he is a single person with nobody to report to, he might as well charge according to his wish, and in case he knows that you don't have any other option, you are in for a treat!
This is why it is best to go for online computer support services. The professionals are well-trained, which makes them proficient enough to handle all kinds of requirements wart. handling computer-related issues. Further, since they are governed by a company, their charges are fixed, and much lower than independent technicians, thus negating the need for you to pay extra. Finally, since the company has many technicians on its payroll, you would never face a problem related to availability. So what are you waiting for? Go get your computer secure now, with online computer support.

Excel Formulas - Announcing 3 Priceless Steps For Effective Writing
Sitting in front of your computer to write formulas in Microsoft Excel is an art. You can get the same result using different functions and logic.
So, there is no a straightforward step by step procedure you listen and follow in any given case.
Additionally...
The fact that you cannot understand errors while you write an Excel formula or ignoring what the reasons of a wrong output are; frustrates you.
If you write a formula before knowing some basic principles, you will keep struggling...
With time you develop your own strategies. Here, I will show you three simple tips you can implement right away in your spreadsheets...
Know in advance the syntax of the Excel function. You cannot guess in the middle of a jungle of parenthesis and commas; Excel doesn't wait you. Once you hit enter, the program runs the algorithm of the involved functions so you could get two things: 1) a wrong result or 2) a message that Excel is unable to process the formula due to lack/excess of inputs. Once you start writing a formula on the formula bar or cell, you must be sure what the arguments of the function are and where they are located in the sheet
Make mistakes before you release a formula. Why to be scary with a new formula? Making mistakes is the best way to gain confidence about how the functions work and also gives you the sense of trust when finishing a formula. I used to create test arguments (usually 1s and 0s) and then I run the formula with clearly expected results. It is easier then to feed the formula with real inputs and be sure of the result
Check the results by hand the first time you use the formula. This is a must since Excel does not show you the Math behind the function wizard. It is your responsibility to check that the formula makes the computations you expect. Do this check with the real-world formula (Math, Statistics, etc), parameter by parameter, you must get the same results. How to do it? Use a scientific calculator
Conclusion
The worst thing you can do is to use a function before knowing the arguments and testing them. You will suffer of three main problems: being prone to errors, inability to detect errors and lost confidence in the results of the formulas you write.

Best Free Registry Cleaner Review
All versions of windows today come with a central information storage component known as the registry which holds your systems configurations relating to hardware devices, software and profiles in the form of keys. Unfortunately it is the constant changes to this database over time that eventually causes functionality issues within windows which requires a free registry cleaner to effectively repair it. It would be great if all computers could always operate as if they were brand new but this not the case as all of us will resort to adding and removing software over time. So what causes the registry to become full of errors and why does it cause problems?
Whenever you change the hardware and software on your system it causes entries to change within the registry which eventually causes this database to become bloated with a large amount of outdated information. These obsolete and empty entries usually come as a result of partial software removals which leave residuals behind and consequently cause windows to suffer in terms of performance when it has to read information from the registry during operations. What free registry cleaner programs do is they automatically repair errors within this component and also perform defragmentation which helps eliminate the data spaces which are created after the problematic entries have been deleted. This increases window's ability to reference information and ultimately results in a more optimized system in which you will greatly reduce program functionality issues amongst other things.
You will know if you are having problems with your registry as you will experience recurring error messages, missing DLL files, deleted desktop shortcuts, unused menu items and possibly even the notorious blue screen of death which indicates failure of an important startup hardware or software component. You can avoid this happening by using the best free registry cleaner available.
When it comes to selecting free registry cleaner tools I highly recommend Reg Cure which has proven its worth as the most popular pc repair tool on the internet today. If you would like to download your free version and scan your computer now please check out the link below.

Registry Repair Tool - Making Windows Registry More Consistent
The Windows Registry is one of the most essential components of the Windows operating system, which is critical to the proper functioning of a computer system. It is a database that is used to store information and settings for all the hardware, software, users, and preferences of the computer system. However, the Windows Registry is very much prone to errors that might hamper the smooth functioning of the computer. It is therefore, recommended to use a registry repair tool for recovering the Windows registry from various registry-related problems.
There are several causes that can create problems in the registry. The primary cause behind this is identified as the overflow of registry entries, and this is generally caused by continuous use of Windows Registry, incomplete installation and uninstallation of applications, and various spyware keys. These problems gradually affect the performance of your system, and soon your system starts responding very slowly. In such situation, you can use a registry repair tool, which you can purchase online from various registry repair service providers. Many a times you can avail the trial version of these tools as registry repair free downloads, where these tools can be freely downloaded with either limited features or for a particular period of time. You can upgrade it to the full version or you can buy the license for unlimited usage.
The registry repair tool is nothing but a computer program that is developed to refine the registry inconsistencies in your system. Therefore, it is also known as registry repair program. The primary function of this program is to scan your system efficiently and effectively to identify and delete the unnecessary registry entries. This minimizes the registry problems and enhances the system performance. Most of the registry repair tools offer registry backups before deleting the unused registry entries so that in case you need any particular entry in the near future, you can restore immediately from the backup. This helps in keeping the registry up-to-date.

Time Value Formulas in Microsoft Excel - Part II
In the first article, I discussed the PV and FV functions in Excel for calculating the time value of money. In this article, I will discuss the NPV and IRR functions in Excel. In the real world, these two formulas are critical in capital budgeting alternatives, as the results determined by NPV and IRR dictate whether or not to commence projects.
NPV and IRR are inexorably linked, as you will find out, but in order to provide the proper reference, some background of the financial theory is appropriate.
NPV is net present value and it is used to calculate what the present value of a stream of future cash flows is based on a specified discount rate. The discount rate is a measure of risk in the cash flows. As a business, you would use the weighted average cost of capital ("WACC", see other article on weighted averages) as the discount rate, as the WACC is the cost of doing business. If you are an investor, you are likely to use as a discount rate your returns threshold over the period of this project. A simple way to think of discount rate is to consider it the minimal acceptable return for doing a deal.
The form of the NPV function is =NPV(rate,values), where rate is the discount rate and values are either nonadjacent specific numbers (A1,C1,E5,G7) or a set of values in rows or columns that are adjacent (A1:N1). As an example, if you make an investment at December 31, 2008 of $50,000, and you are going to receive $9,000 at the end of each year for the next ten years, the NPV of that stream of cash flows would be $4,819 using a 10.0% discount rate. If your minimal acceptable return is 12.0%, the NPV is $761 and if the minimum acceptable return is 15.0%, the NPV is -$4,201.
For positive NPV values, you would accept the project because it is adding value. In the instance of a negative NPV, you would not do the transaction. In general, you DO NOT accept projects with negative NPVs as that is an indication of value erosion (the return on the project is less than your required minimum so you are subtracting value over the time period of the project).
IRR is the internal rate of return and is used to calculate the compounded rate of return over a series of cash flows. In finance, the IRR assumes that each of your cash flows is reinvested at the calculated IRR. In other words, if your IRR result is 4.0%, each of your cash flows is assumed to have been reinvested at that rate to get the proper IRR. A more important feature of the IRR is its relationships with NPV: the IRR of a project is the rate at which the NPV equals zero. Thus, you should begin to see how these two functions are interrelated.
The form of this function is =IRR(values). In this case, the values must be adjacent or you will get an error message. Sticking with our prior example with the $50,000 investment and $9,000 cash payments, the IRR on that stream of cash flow is 12.4%. Based on what was stated earlier, you should have begun to suspect that the IRR was close to 12.0% because the NPV at a 12.0% discount rate is $761, or closer to zero than a 10.0% discount rate. In short, the IRR provides the bottom return at which you would be able to accept any project.
The problem with the IRR function and IRR in general, is that there can only be one change in sign of the cash flows. This is commonly achieved by an investment (negative sign) with payments returning to the investor (positive sign). If there are two changes in the signs of cash flows, you may get an incorrect IRR as there can be more than one. Additionally, the IRR formula assumes that cash flows come in at the same time over each period (end of each year, end of each month, etc.). If this is not the case, you will have to use the XIRR function, which considers different times for payments over the project period. Finally, as was mentioned earlier, the IRR assumes that the cash flows are reinvested at the IRR. If you know that reinvestment rates will be different over the time horizon of the project, you should use the MIRR function, which allows for you to input a specific reinvestment rate.
As a final thought, NPV and IRR are good tools for determining whether or not to pursue a project, but what if you are evaluating two mutually exclusive projects (you can only choose one) and you get conflicting answers? This can happen when Project A has a higher IRR and lower NPV than Project B. If you can only choose one project, you will always choose the project with the higher NPV, and in this case that is Project B. Why is this? The fundamental premise in finance is maximization of value. A higher NPV means that more value is being created for the shareholders and that is the project you want to choose.

Windows XP: Genuine Disadvantage
Windows Geniune Advantage (WGA), Microsoft's latest antipiracy measure, is causing headaches for Windows XP users who've been good about loading the latest security patches for Windows and Internet Explorer (IE). Why? Two reasons:
(1) Initial attempts to download and use WGA may give you an erroneous error message stating that valid product keys for your genuine version of Windows XP are invalid. It's not surprising that an earlier version of WGA was hacked within 24 hours. Computer technicians everywhere were faced with another change to Windows software requiring they either troubleshoot the problem or find a way to bypass it. Thus, another hack was born. Why does WGA initially report that valid product keys are invalid? Basically, because it's encountering a problem it doesn't know how to interpret differently. The problem is:
(2) You need to re-enable ActiveX for WGA to run. ActiveX is a purely Microsoft technology that integrates interactive content on web pages, like Java applets. WGA can't run without ActiveX. Unfortunately, ActiveX has been exploited by hackers who discovered vulnerabilities in the technology and use them to run their own malicious software on your computer. As a result, one of the Windows updates you ran in the not so distant past turned off ActiveX to block this vulnerability. There's the catch: You can't run Windows Update until you validate your license with WGA which won't run until you re-enable ActiveX and lower your browser's security so you can load new security patches! Good thinking!
Microsoft's support page (in typical "microspeak") does warn you that you are potentially exposing your system and that you will want to re-enable your browser's security after you help Microsoft make sure you aren't stealing Windows:
Important These steps may increase your security risk. These steps may also make your computer or your network more vulnerable to attack by malicious users or by malicious software such as viruses. We recommend the process that this article describes to enable programs to operate as they are designed to, or to implement specific program capabilities. Before you make these changes, we recommend that you evaluate the risks that are associated with implementing this process in your particular environment. If you choose to implement this process, take any appropriate additional steps to help protect your system. We recommend that you use this process only if you really require this process.

CYA We designed WGA to run off of ActiveX technology, software components we know will make your computer vulnerable to attacks because we wrote ActiveX (that's right, we created it) and left a lot of holes in it that could be exploited. Basically, you'll need to re-enable ActiveX and make your system vulnerable so that WGA will work the way we designed it to work. Then and only then can you get the latest Windows updates to make your system run, um, "safer." But first we recommend that you decide for yourself that you really need to run WGA, so that you can't come back and sue us if you're computer is attacked by a virus while you're running WGA to validate your license which we also made you validate when you bought your computer, which of course came with Windows because we own 99% of the market (tee hee). But anyway, we like to see you jump through hoops and make you repeatedly prove you own it because Microsoft is "antitrust." Oh, and when you're done, don't forget to make your system, um, "safe" again by turning on whatever you use to block ActiveX or load our cool WGA ActiveX control, which is basically just a toggle that turns ActiveX on and off whenever we feel like exposing your system to more security risks so you can load more security patches that will work until someone figures out they don't.
The earlier version of WGA was compromised and I expect that the current version will be too, if it hasn't already. As usual, tech savvy people get around measures designed to protect copyright, and less tech savvy people are left pulling out their hair trying to figure out ways to undo what Windows does for programs to "operate as they are designed to." Microsoft continues to prove it needs better designers. They can't seem to get away from ActiveX although other programs do just fine without it. (Mozilla Firefox doesn't use ActiveX to enable web page interactivity. That doesn't mean it's 100% safe, but I've never had to lower security to patch Firefox.)
Microsoft needs to get rid of WGA. It's completely ridiculous to have to lower security to run patches designed to heighten security; and in this case Microsoft wants you to do that entirely for their benefit, not yours. Microsoft argues software piracy is costly for everyone and so antipiracy measures help you. That may or may not be true, but it's not the point. WGA is simply a bad antipiracy measure. It's a backdoor approach that won't stop or even slow down piracy. Both genuine and counterfeit versions of Windows will still run without the updates, which means:
Users who know they have a counterfeit version won't validate, won't run the updates and will still enjoy the use of Windows;
Users with a counterfeit version they unknowingly purchased through a disreputable OEM vendor, online auction or software pirate will simply think Windows is broken, will forego further updates, forever curse Microsoft, and possibly purchase a Mac. At any rate, very few will ever realize they have a counterfeit version and are unlikely to add to Microsoft's bloated profit margin; and
Licensed users with the geniune product and valid product keys will continue to have to prove ownership if they want to run needed updates and will have to expend more time and money troubleshooting what Microsoft does to protect its own interests, will forever curse Microsoft, and eventually purchase a Mac.
Antipiracy measures have to be applied at the source, not at the user end. Microsoft may achieve better results through more controlled production of its software products at the assembly line. However, the company has been greedy. When you rush to market with a product you want to make as widely available as possible, you take shortcuts. Now Microsoft is backpedaling in an attempt to recoup its perceived losses. It's being shortsighted and selfish and may well lose money in the process. By implementing WGA and other user-end antipiracy measures, Microsoft does little to affect software piracy - and increasingly antagonizes its paying customers.
Imagine driving down the street in your car and being pulled over every other block so you can show your car title. "Yes, I own it. Yes, I own it. Yes, I own it." Microsoft rolls out updates on the second Tuesday of each month as needed. So, pretty much every second Tuesday of every month you have to lower your Internet security just so you can say, "yes, I own it."

(1) Initial attempts to download and use WGA may give you an erroneous error message stating that valid product keys for your genuine version of Windows XP are invalid. It's not surprising that an earlier version of WGA was hacked within 24 hours. Computer technicians everywhere were faced with another change to Windows software requiring they either troubleshoot the problem or find a way to bypass it. Thus, another hack was born. Why does WGA initially report that valid product keys are invalid? Basically, because it's encountering a problem it doesn't know how to interpret differently. The problem is:
(2) You need to re-enable ActiveX for WGA to run. ActiveX is a purely Microsoft technology that integrates interactive content on web pages, like Java applets. WGA can't run without ActiveX. Unfortunately, ActiveX has been exploited by hackers who discovered vulnerabilities in the technology and use them to run their own malicious software on your computer. As a result, one of the Windows updates you ran in the not so distant past turned off ActiveX to block this vulnerability. There's the catch: You can't run Windows Update until you validate your license with WGA which won't run until you re-enable ActiveX and lower your browser's security so you can load new security patches!

Always Use Efficient Security Applications
As a computer user I always use to search for the best security that I can get from the web to make my system secure. I found many, downloaded and installed some but still I am seeking more.
Instead of installing different applications, I wanted to have a single security application that can secure my system from viruses, spywares, and also protects my data from hackers at the same time but wasn't able to find one, however the alternatives I downloaded are doing good job for me.
There are numerous security applications that you can find on the internet but it's really hard to choose the best one, some of them are free and for some you have to pay. Computer users usually have to face problems like virus attacks or spywares affecting the performance of their systems and hackers who intrude into their computers and misuse their important private data.
As the software industry is growing rapidly, they have developed many security applications to provide security to the computer users for example to deal with viruses they created McAfee anti virus software, avg and many more, these softwares are doing a good job for its users, they just do not secure your system from viruses but also removes them.
The problem which most of the users face is the security of their personal data, many data protecting softwares are also available for this purpose but still the problem is "which is more secure and efficient?. I personally think to use a reliable data security software either it's free or I have to buy it, but the security of my personal and private data is that can never be ignored at any cost.
Computer have become a necessary for us and it depends upon us to leave it in the hands of dangerous viruses and hackers or secure it using and selecting an efficient and effective security application.

Speed Up Your Slow Computer With a Windows XP Registry Cleaner
Are you using a computer that is running slow all the time. Using a computer that keeps freezing is not just annoying it is a sign of potential trouble with it as well and it is important that you fix it quickly.
Many people just go out and buy a new computer thinking it is too old or too expensive to repair when it is really easy to speed your slow computer up quickly.
Most of these errors can be traced back to the database known as the registry. This is where all the information about the computer configuration is stored and what happens is as more programs are installed the registry becomes larger and entries become corrupt and outdated and it is this that slows the computer right down.
By correcting these errors you not only speed up your computer but stop it from crashing and even failing to start windows.
The first thing is to remove any programs you do not use and then check for any programs you do recognise. Do just assume someone else in your household has installed them. This is how adware installs and left on there will generate useless pop ups every time you use the internet and slow your computer to a halt.
The next step is to run a registry scan on your computer. This can be done free and will report any errors or corruption that might be slowing your computer down or that can cause it to crash or worse. Once you find any errors you can remove them at the click of a button.
