I have installed Windows Server 2003 R2 Standard Edition (x86) onto a machine and activated it using the wrong product key. Is there a procedure to reenter and reactivate Windows with the correct key that does not involve reinstalling the OS?

You can use Magical Jelly Bean Key Finder

That shows the key but I can't find an option to change it or to reset activation. Nov 9, 2009 at 21:38

1Sorry about that, the updated version removed that functionality. Try this version: magicaljellybean.com/files/keyfinder.v1.51.zip Make sure you backup your activation files first. Nov 10, 2009 at 21:10
Check out this article, its for XP, but should work all the same. You need to basically deactivate your copy, then instead of re-activating, change the key. Make sure its the same type of install media that the new key comes from. (Retail, OEM, VL)
