Windows 10 Refurb License

Usualy at work wen we prepare refurb computer that were on windows 7 we have to void the coa near the windows 7 key, that is easy to do.

My problem comes with the Windows 8 version were the key is hiden in the bios.

I can extract the key but that doesnt give me the coa only a key.

I have figured out that if I reinstall windows 8 on the computer and activate it with the key that is in the bios, then I will get a COA in clear text the same as on a label

Can I void that coa to put a refurb windows 10 key on the computer ?

If yes is there an easier way to get the coa witout having to install windows 8 over again before I can install windows 10 with a refurb key.

 

Windows 10 Activation (Insider)

How long did you wait for activation?
When I re-installed with a fresh install... it took a few hours to sync and activate.
However, it did, finally, activate.

 

DOWNLOAD WINDOWS 10 NOW - Upgrade and ISO direct from microsoft

Click to expand... Yeah I went to that site, why do I need to buy a key?
I won't buy a key, stupid.

I'll revert back to windows 7 then.

When I still was on windows 7, about a year ago I added 4GB extra ram which is a total of 8GB now,
is that causing the problem?
