Windows 10: Windows 11 keeps reverting license key

I have a computer with windows 7 product key I bought back in 2010. Since I needed another computer I bought a laptop, but it came with Windows 10 Home Single Language, so I used the windows 7 key from the other computer I'm not using anymore on this one. The key works and it activates Windows 11 Home Single Language installed on my PC to Windows 11 Home. Problem is, it reverts suddenly back to Single Language after some days passed, or after updates, I'm not sure.

Windows 10 update cause Bad Pool Header at login


All BBBBBs indicates a VLK (Volume License Key) which cannot be used for activation. You real key will be on a COA sticker somewhere on the computer.

You won't need it though. As long as Windows 7 is activated, Windows 10 will be happy and will not ask you for a key.

See my post here for suggestion before trying the next upgrade. I reverted to 8.1, next steps to try 10 upgrade again... - Page 2 - Windows 10 Forums

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?
