product key transfer?

I had a computer I built start slowing down a few months ago, so I rebuilt and purchased a new windows 7 key. However I was wondering if I could install windows 10 on a new htpc and use my old windows 7 product key for authorization? That key is no longer in use because I got rid of the computer. I have heard windows 10 does great on low powered devices so I would love to give it a try and my htpc box

As long you bought a retail version of Windows 7 you can transfer the key on to the new system. OEM versions are not transferable. Was your version a boxed retail version?

no it was the oem version

Those are tied to the motherboard they were first installed/activated on. You'd need to buy a new licence for the new device as you can't transfer those.

OR was it OEM SYSTEM BUILDER.

I didn't think system builder licences on 7 were transferable. Although must admit, I've never actually bought one.

depends on whether it was NSLP.
(basically the N means not tied to a motherboard.)

Interesting, I didn't realise different system builder licences existed.
I assume it's the system builder licences that come in the retail card envelopes that are transferable then?

Correct.
