Windows 8 Activation issues

[sc1997]

So I have my Windows 8 Pro copy that I bought a while back. I purchased the upgrade pack and did a clean install and, for some reason, did not have any problems.

Now I'm about to do another clean install so I was wondering how to go about the activation process. Do I have to deactivate or just format the drive? How can I let Microsoft know it is actually a clean install of the same copy and not an install in another machine?

Thanks!

I believe that both Windows 7 and 8 have a 3 or 5 key activation limit per key, and once you go over that limit you have to call up Microsoft. 

When you call Microsoft I am not sure if they reset your key or if they just give you a new one altogether. If you haven't installed more than once you are in the clear.

You don't have to deactivate.  Just do a clean install.  It'll activate just fine.

 

Since Windows is on the drive already I assume the fact that it's an upgrade key won't be a problem.

If anything arises just call Microsoft and tell them you are reinstalling the OS. I do it all the time, no big deal.
