Tip & How-To about Computers & Internet
The message is prompted by Microsoft Windows WGA (Windows Genuine Advantage) software.
To start I must advise you that the best thing to do is contacting Microsoft, and asking them as to proceed, as the system installed on your computer may be counterfeited.
See:How and when to contact Microsoft Customer Service and Support
If you get the Microsoft Genuine software warning, that usually means that the installed system key is not recognized as valid. This often happens when the system is installed with a number that is not the one printed in the sticker.
In some case the WGA message was prompted in presence of genuine Windows installation because of a system bug.
If you have a Windows version that is the same as the license number printed on the COA sticker, then the best thing to do is changing the number and then validating Windows again. See here:Genuine Microsoft Software.
If your installed software is a different version from the one you have a valid COA (eg. XP Home Edition on sticker vs. XP Professional installed), then you must install the Windows version for which you have the license or purchase the proper license for your system. Any unlicensed use of Microsoft software will be illegal.
In case you want temporarily need to remove the Genuine Microsoft Software warning before installing genuine software, you can follow the steps below.
Method 1 System Restore.
A system restore to a date before the warning started will stop the message.
The restore will set the the computer to the same state it was in the date before the warning message started.
The data will not be deleted, but all settings and software installed after restore date will be affected. Do a backup of your data before starting system restore.
See: How to perform System Restore on Windows XP
Method 2 Software utilities.
There are several utilities to remove the WGA logon message. Try the ones listed below.
Remove WGA 1.2.exe.
Method 3: Delete software and change registry values.
You can get rid of the message changing the registries below. Do a backup of Windows registry before starting. If you change te wrong registry entry, Windows may not start. If that happens, then you will have to get rid of the problem installing a genuine Windows.
Launch Task Manager.by pressing Ctrl Alt Del at the same time. Look for the process “WgaTray.exe” and stop it.
Start computer in Safe Mode and delete the file WgaTray.exe from c:\Windows\System32
Delete WgaTray.exe from c:\Windows\System32\dllcache
Type Regedit in Run box and open Registry Editor.
In Regedit find the entry called : HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon\Notify key.
Delete the folder WgaLogon and all of its contents.
Restart the PC normally.
The methods to remove the WGA message are not a solution to the problem. The procedures illustrated will remove the warning, but the system will not be properly licensed. Arrange reinstall of the system according to Windows version listed in your COA , or purchase a valid Microsoft product.
