Question Use Replacement Key To Activate Windows?

In relation to the problem I detailed in this thread:-

Question - Win7 Pro 64 Reported As Not Genuine

I've had this PC since 2016 when I activated the 100% genuine Win7 Pro 64. No problems since then in this respect until earlier today. Suddenly I get a pop-up saying this 6 years old fully updated by MS until Win7 supported ended is now, mysteriously not genuine. Pretty sure this must be...

forums.anandtech.com

What I'd like to know is if I buy a genuine matched new copy of Windows 7 Pro 64 OEM can I use the COA Product Key from that as a new, replacement key for the existing Win 7 installation?

I really don't want to do a new install from scratch whether that is with the original genuine disc/key or a new disc/key.

Thanks but that thread doesn't help much. What I was interested in was whether using a (obviously genuine) new key, whether it fails to work or not, might invalidate that key so it can not be used with the genuine MS Win7 Pro 64bit OEM disc it came with.

I've posted the MGADiag results here in that other thread and as far as I can see there's no obvious problem.

In the cases I've looked at the problem has been a Licensing one and there's been something wrong in the Licensing Data section of the MGADiag report but I can't see anything like that my one.

if you buy a retail non oem key from hrkgame.com and register it with MS by making a MS account, that key will be attached then for any other computer upgrade and will self activate anytime you redo windows with that key anytime you do a redo and sign into store. If you redo your pc with a windows 10 and use a windows 7 x64 key that has not be registered or registered in a very long time, can use it when you activate windows 10, and then make a account and then that key will do the same. I have not bought a "key" after buying my first one for my computer.

Interesting suggestion. Thanks.

Can any Windows OS key be registered with MS - I already have an MS account (XB360 game purchases required it)?
