How to ACTIVATE Windows XP without any software!!

This is a simple but effective registry hack that has been tried and tested several times by me and it works!!
If you don’t believe me then try this for yourself!

1 – Start menu/run/ type “regedit” and press enter,
this will take you to the registry editor

2 – Now follow this directory:

3 – When you get to WPAEvents in the righthand column there should be “OOBETimer”
right click it and go to “modify”
Change the numbers in there to :

FF D5 71 D6 8B 6A 8D 6F d5 33 93 FD (this works with Windows XP Home and Pro, both 32 and 64bit versions)

4 – When you’ve entered them, right click on the file “WPAEvents” and go into “permissions”

5 – In there highlight “SYSTEM” and underneath it check the two boxes under “deny” and click “OK”

Phew thats it!!! I know it looks complicated but it’s really easy, it just requires patience.

I tried this when I used up the amount of times you can activate Windows XP, it worked a treat!

To check that Windows is activated, simply click on Start menu/All Programs/Activate Windows.

It will say “Windows is already activated”.

    However, now I get the Windows warning:

    Your Windows product must be activated within 3 days.
    Do yo want to activate Windows now?

    YES NO

    Will I have to reinstall Windows in 3 days or should I simply
    ignore the 3 day deadline since Windows is already

    • Sorry i’m Late to reply. but i think is OK.
      what WinXP in your comp it is the SP1, SP2, SP3., Professional, Home or the other version. maybe you need to turn off the automatic updates in your OS. and what key you use to install the windows.
      may be the problem is on the way you install the windows.
      if you confuse, you can e-mail me
      ill try to help you solve the problem.
