Make your wndows Xp GENUINE.!!

1) start > run > "regedit" (without the quotes of course)

2) go to the key:HKEY_LOCAL_MACHINE\SOFTWARE\MICROSOFT\Windows NT\CurrentVersion\WPAEvents\OOBETimer...and doubleclick on it.
Then change some of the value data to ANYTHING ELSE...delete some, add some letters, I don't care...just change it!now close out regedit.

3) go to start > run > "%systemroot%\system32\oobe\msoobe.exe /a" (again, dont type the quotes)

4) the activation screen will come up, click on register over telephone, then click on CHANGE PRODUCT KEY, enter in this key: JG28K-H9Q7X-BH6W4-3PDCQ-6XBFJ.

Now you can doenloads all the updates without activating,
and the Genuine Microsoft Validation thingy won't bug you no more!!
Works with most WinXP versions though ther r some exceptions...
