Windows 8 upgrade key

I have Windows 8.1 installed on my old pc with Windows 8 upgrade key. I'm wondering can I reuse the same Windows key on my new pc if I uninstall windows on the old one?

One key to one pc to my knowledge.

I ran into this issue with one of the OS's. I called Microsoft and they helped me out. You just have to explain to them what your doing. At least that worked a few years ago.

If you uninstall both win 8.1 and then win 8 from the old pc, then yes, you can use the win 8 upgrade key on a new pc again.
