1) start > run > “regedit” (without the quotes of course)
2) go to the key:
HKEY_LOCAL_MACHINE\SOFTWARE\MICROSOFT\WindowsNT\CurrentVersion\WPAEvents\OOBETimer
…and doubleclick on it. Then change some of the value data to ANYTHING ELSE…delete some, add some letters…..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 do all the updates without activating, and the Genuine Microsoft Validation Thing won’t bug you no more!!
