This procedure described below will allow you to bypass the Microsoft Genuine Validation.
I hope this is the best way to make your copy of windows xp geniune.
1. Click START>RUN and type 'regedit'
2 Registry window will be opened, Then Go to
…and double click 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 (Professional XP ONLY)
BQJG2-2MJT7-H7F6K-XW98B-4HQRQ (Home Edition ONLY)
If the above keys are not working, report me...
Now you can download all the updates without activating, and the Genuine Microsoft Validation will **** you No more.
Note: This works better after reformat.
