When you attempt to check the validity of your Windows XP license using WGA (Windows Genuine Advantage),
it is not successful, and your receive:

And if you are "really lucky", you will get locked out of your legit, and validated Win XP installation !

This is the price you pay, for the "added security" you get when running your WinXP from a non-administrator account.

The problem is that the WGAN application requires write access to a data file that it installs
without regard for the permissions that are required to allow ordinary users access.
We would hope that another edition of this update will be released in the near future to address this.

More spesific :

This behavior will occur when you do not have the required permissions on the
%systemdrive%\Documents and Settings\All Users\Application Data\Windows Genuine Advantage\Data folder.

To workaround this issue, grant the local users group both Read and Write to the \Windows Genuine Advantage\Data folder:

01. Start / Run / %systemdrive%\Documents and Settings\All Users\Application Data\Windows Genuine Advantage\Data / OK.

02. Right-click the Data folder and press Properties.

03. Select the Security tab.

04. Select Users (<ComputerName>\Users) and check that the Allow column has Read & Execute, Read, and Write checked, and that the Deny column has no checks.

05. Press OK.

06. Try using WGA. If this step is successful, exit this procedure.

07. Shutdown and restart your computer.

08. Press F8 on the Boot menu.

09. Use the arrow keys (with Num Lock off) to select Safe Mode and press Enter.

10. If you have more that one operating system installed, use the arrow keys to select the appropriate installation and Press Enter.

11. Open a CMD.EXE window.

12. Type RD /S /Q "%ALLUSERSPROFILE%\Application Data\Windows Genuine Advantage" and press Enter.

13. Restart your computer normally.

14. Use WGA to validate your license.

damn... im pretty lucky... i didn't have install it last time i update my PC!
Also, thx you bearcat for this walkthrough!

My computer said that I should update and install it.. So that it could help me find out if I was using a illegal copy or not then report me to places where I may or may not purchase it from. What a "nice" program!
