Make Your Window Xp Geniun!!

This will allow you to bypass the Microsoft Genuine Validation thingy

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 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 download all the updates without activating, and the Genuine Microsoft Validation thingy won't bug you no more!!
