Thanks for that post woodboss, if I hadn't of looked down at the replies I would've hosed my present install and gone through the trouble of another install of all the products that I'd traded my butt off to get.

Having done this myself a few times Answer # 1 is the most correct buut would also add this tip, copy and paste the command into the "run" dilog box as there a lot of characters to type in it is very easy to misstype a character,
The other Tip is make sure you have a valid CD key to enter other wise you could be trying for a very long time as there endless combinations to try, once you have this valid CD key do ypourself a favor and keep it somewhere safe (just incase you have to do it again for some reason, it could save you a headache or two)
Hope tis helps in some way :-)

Answer number 4 works just fine. I tried this a couple of times myself and it works great.

Answer 4 is wrong. That command allows for Windows activation, not for CHANGING of the Windows product key.

addendum: That is assuming Windows product in question has already been activated with another product key and for some reason one wants or needs to change the key. If Windows has not been activated, then Answer 4 will work.
