TRY TWEAKNT
TweakNT is a utility that allows you to remove the timebomb and change the edition of any NT OS.
It should be fairly self-evident how to use it, if it isnt, I would suggest you don't even try,
as you'll most likely break something.
Notes:
Timebomb is not the same as WPA, timebomb is usually present in betas, and is normally somewhere between 120 and 360 days.
If there is a timebomb, the build will always be shown on the desktop, consequently, removing the timebomb will remove the build from desktop (unless you specify it to always show)
