How To Remove Windows Genuine Advantage Notification (WGA)

What is Windows Genuine Advantage Notification?

Windows Genuine Advantage is a software anti-piracy program started by Microsoft in 2005. It enforces the online validation of some of the Microsoft products. It is automatically installed if Windows Automatic Updates are enabled. If goes to the Windows Update site, it will ask you for installing this validation tool before you can select the updates from the Microsoft update website. By accepting to install this validation tool, an ActiveX component in Internet Explorer is installed.

What does it do?

If, for some reason, this tool fails to

validate your Windows, then it’ll always show you a warning that you may be a victim of software counterfeiting and that your Windows is not genuine. It will show up on your logon screen and make you wait for some seconds. And when you logon, it will just site in your status bar and will keep annoying you.

Here is the description of Windows Genuine Advantage Tool from Microsoft.

When this tool is installed, it shows up before logging on to the system

And keeps on displaying the balloons in the status bar.

Windows Vista

Windows XP

What data does WGA collect?

This tool, if installed, collects the following data from the system.

• Computer make and model
• BIOS checksum.
• MAC address.
• GUID
• Hard drive serial number.
• Region and language settings of the operating system.
• Operating system version.
• PC BIOS information (make, version, date).
• PC manufacturer.
• User locale setting.
• Validation and installation results.
• Windows or Office product key.
• Windows XP product ID.

How to remove WGA notification:

There are several ways to disable WGA notification. Some of them are given below:

1- Through Firewall

WGA notification can easily be disable through your firewall. You can disable the automatic startup of wgatray.exe and wgalogon.dll through your firewall. This will disable WGA notifications and this will do no harm to the system.

2- Through third party softwares

There are many softwares available which can disable WGA notifications. Notable softwares include WGARemover and MUBlinder.

3- Through System Restore

If you have installed WGA by mistake, you can always use your system restore to get rid of it. Restore your system to the point where WGA was not installed.

4- Through deleting files manually

To remove WGA manually, follow the steps below:

• Download this bat file
• Double click it and restart your system
• Most probably, you have successfully deleted all the files used by WGA. Now it should not come at logon.

If this bat file does not work, you should manually delete the following files from your system:

• X:\Windows\System32\wgatray.exe
• X:\Windows\System32\wgalogon.dll
  (Where X is your Windows Drive)

And you must also create an empty wglogon.dll file in the same directory from which you are deleting it.

Restart your system once you’re finished. If you are having problems with following these steps, please write in comments.

Creating CON folder

If u hav not heard of CON folder,, try creating a folder named “con” in windows.

u cant create it directly…

bcos CON is the name assigned for windows configuration folder by microsoft.

n similarly named folders can create confusion 4 th os. so creating folder named “con” is impossible.

although u can create it using the method below, the folder is useless, u cant use it nor delete it.

Follow these steps to create CON folder :-

——————————–

STEP1: goto command prompt

STEP2: and type md \\.\\”c:\con” (with quotes, better you copy and past it)

the above command will create the folder named “con” in Drive C:

To create that folder in your desktop (for Windows XP) replace the ‘c:\con’ with the FULL PATH of your Desktop, Below is an Example:

md \\.\\”C:\Documents and Settings\USER\Desktop\con” (Where USER is your USERNAME)

(You MUST specify the full path within double quotes [“] If it contains spaces)

In Windows 98, your Desktop path would be : C:\windoiws\Desktop (where C: is the drive letter if your Windows installation)

That is all about creating the folder.

BUT DON’T STOP HERE
Because after creating such a folder, you can’t delete it by simply pressing the DEL key.
To delete this kind of folder, use the same command replacing MD with RD. For example:

rd \\.\\”c:\con” (with quotes for path containing spaces)

BUT DID YOU KNOW?, there are also some other names which you cannot use for a folder. For exapmle Try to create a folder with these names:
AUX, COM1, COM2, COM3, COM4, LPT1, LPT2, LPT3, PRN, NUL

more info can be found here–> http://kerneltrap.org/node/5772

======================================…
NOTE: PLEASE BE CAREFUL WHEN MAKING ANY FOLDER USING ABOVE NAMES, AS THEY MIGHT CREATE SOME PROBLEMS IN WINDOWS
