Recently I bought and installed Windows 8 Professional. Some time later I bought an SSD drive and cloned the original disk (with Windows 8 on it) to the new one.

Now I have problems with it, since I forgot to change partition align and some other things, I have some problems with this installation at startup (strange errors appear when the computer wakes up from hibernation).

I want to do a clean install to the SSD drive, but my Windows copy is already activated. If I format my SSD drive and install Windows 8 Professional on it, can I use the activation key that I have already used, to activate the new Windows installation? All hardware is the same, except for the hard drive.

A simple hard drive or minor hardware change shouldn't cause any problems at all with activation. Otherwise lots of people would be up in arms. – Karan Oct 29 '12 at 7:01
Even if I run installation and activation process twice? – Lazin Oct 29 '12 at 7:24
Yep, every time you reinstall you'd need to re-activate. If they restricted it to just a single activation and didn't allow for the possibility of any hardware changes, they'd be shooting themselves in the foot. – Karan Oct 29 '12 at 7:28
I second that. I can't cite anyone, but I've done this a whole lot of times. – Henning Klevjer Oct 29 '12 at 8:19

To answer your question. Yes you can reuse your Windows 8 key regardless of hardware changes or machine.

Edit: With 10 reuses as Karan has explained. (Thanks! :)

... within limits (I believe it's 10 activations per key if hardware has changed). – Karan Oct 29 '12 at 7:33
Thank you guys, my doubts is completely vanished :) – Lazin Oct 29 '12 at 7:56
