How to bypass WPA (Windows Activation) on Windows XP
Tested on Windows XP Professional SP2 and Windows Server 2003 R2.

First, click “Run…” on your start menu, type “regedit” and press enter.

The Registry Editor opens up, and you are presented with a long list of keys on the left.

Browse through the list to HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindows NTCurrentVersionWPAEvents.

On the right, you should see a stringz value named OOBETimer.

This is the activation stuff. If you change it, Windows will change it back within a few seconds.

Whatever its value is, change it to FF D5 71 D6 8B 6A 8D 6F D5 33 93 FD.

After you’ve changed it, right-click WPAEvents and choose “Permissions…”

Under “Permissions…” for WPAEvents, Go into the Advanced settings.

UNCHECK “Inhereit from parent the permission entries that apply to child objects. Include these with entries explicitly defined here”

When prompted what course of action to take from here, click “COPY”

From there, Highlight the SYSTEM line, and click edit.

Deny all options, apply, and run a free copy of windows.

If not, just try again. Microsoft owns for making it so easy to hack their software.
So, just keep on enjoying an activated version of windows. swapnil_009 over and out!

THANKS swapnil_009!! Whoever you are!!

So, just to make sure, I run Windows Activation crap again and this is what I get ^^

So…
