Windows 10: I bought a refurbished computer and I can't to activate windows ten. It is a HP pro

I bought a refurbished computer and I can't get it to activate windows ten. It is an HP pro. It wants me to buy a $199 license or have product key. All I do on a computer is buy and sell on ebay. No license required and they did not send me a product key. can anybody help me.

cannot reactivate Windows 10 Pro on computer I purchased from HP refurbished with Windows 10 Pro loaded. Will not accept my activation key to re-activate

I purchased a refurbished HP desktop computer with Windows 10 Pro loaded on it. Initially, no problem. Activation key worked. Then something happened and it says Windows is not activated, and it will not accept my activation key.

 

Windows 10 Pro Refurbisher Install

It wouldn't surprise me if that applies to MAR's.
I've bought many refurbished computers over the years and the stickers on them that looked like the images that have been posted.

I don't know the requirements for MRR's but that's what you probably have.
Can you contact the refurbisher and get them to activate what you bought from them?
--- I’d like to believe they should be able to tell you over the phone what product key to use to get it activated.

Go back to post #2 and use the ShowKeyPlus link Bree provided.
--- Find out what ShowKeyPlus reports.
--- Instead of trying to change a Windows 10 Pro non-existent product key you might be able to use the Windows 8.1 Pro key if ShowKeyPlus records it. I'm not sure how yet, but at least get the ShowKeyPlus information.
