The only reason i am asking this is because i have a windows 8 disc and activation key sitting on my desk and i was hoping that i could sell it even though it is already activated.
If you have a one use key, then it can only be used once. If you try to install another copy of Windows and use the same key, it'll deactivate your other Windows.
Alright thx for telling me
OEM Keys won't work (come with computer), but generic keys have activation limits 2 or 5 depending on where it came from. You'd have to call Microsoft to get it reset.
