For testing purposes only. Build 2600.......What the???

I had a mate do some work on my PC and he re-installed XP Pro for me. Then he applied a Service Pack and now there is this message on the desktop in the bottom right hand corner:

For testing purposes only. Build 2600.xpsp1.020828-1920 (Service Pack 1)



I got hold of another version of the Service Pack 1 from another source and the message remains. Any assistance would be much apreciated. I really just want to get rid of the message if possible.

1.Click on "Start", then "Run.." and type "regedit".
2.Navigate to the registry key:
"HKEY_CURRENT_USER\Control Panel\Desktop".
3.Once there, locate the DWORD value "PaintDesktopVersion".
4.Right click on it and select Modify.
-Value equal to "0" removes Windows version from desktop.
-Value equal to "1" adds Windows version to desktop.
5.Reboot your computer.


Try that.

If it doesn't work, let me know.

Had the same problem after having installed IE7b after i uninstalled it kept the message there checked the value you mentioned above and it is set to 0 so i set it to 1 then back to 0 and still there any ideas?

Disregard I found another solution to this
If the value is already 0 or if this did not fix it then there are 2 keys:
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\SystemCertificates\CA\Certificates\FEE449EE0E3965A5246F000E87FDE2A065FD89D4]
[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\SystemCertificates\ROOT\Certificates\2BD63D28D7BCD0E251195AEB519243C13142EBC3]
Find those and remove them and reboot.
