How to make XP genuine
1) start > run > “regedit” (without the quotes)
2) go to the key:
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 > “%systemroot%\system32\oobe\msoobe.exe /a” (again, don’t 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!
