Windows 10: Microsoft says my 10-year-old Windows 7 CD Key is not valid

Ran for years with it. Upgraded to Windows 10 with it. Have reactivated with it after reinstalls.

Upgraded MB and CPU. Now refuses to activate. Spoke to customer support. They check the key - it is not a valid key.

Is there maybe different parts of MS that do validation, so that it works sometimes and sometimes not.

Is it possible to take a photo of the DVD and labels and send them to MS so they can see for themselves. Or maybe send them the actual Windows 7 DVD and they can see for themselves that it is real. They are not saying the product key is already in use, they are saying it is FAKE.

Installing Windows 10 using Windows 7 key

Nope, you need to install Windows 10 first and make sure the Windows 7 key is transferred to your Windows account after you've installed Windows 10 (not quite sure how that works). I missed the last step and I could not activate Windows 10 after a re-install... Microsoft seem to have done everything they can to make it a PITA. Also, it's technically too late to do this now anyhow, as the upgrade offer has expired. But KMSPico works quite well...

As for getting rid of Windows, delete the Windows folder.

When I upgraded my windows 7 with win10, it says it cant validate my product key? Why? Can you give me the steps to follow to validate it?

 

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?
