Make your Windows XP with Service Pack 2 geniune. Im not sure if this works on SP3.

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
HKEY_LOCAL_MACHINE\SOFTWARE\MICROSOFT\Windows NT\CurrentVersion\WPAEvents\OOBETimer

…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 > type %systemroot%\system32\oobe\msoobe.exe /a and press enter.

4) the activation screen will come up, click on register over telephone, then click on CHANGE PRODUCT KEY, enter in this key:

V2C47-MK7JD-3R89F-D2KXW-VPK3J
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.

Feel free to post comment :)
