Windows 10: Windows 10 key not working on another machine with Windows 11.

I've bought a Windows 10 Pro key Retail version about 5 years ago from a local retailer. I successfully activated Windows 10 Pro on my laptop with it. About a year ago I wiped it and installed Linux instead.Now I have a new PC with Windows 11 Pro. As far as I understand, I should be able to activate it with that key, right? But when I try to do so, I get an error: "The product key you entered didn't work. Check the product key and try again, or enter a different one 0x80041023".I wanted to try activating by phone, but this option is not available. I also requested a callback from Microsoft

:)

Thanks but I don't want to do any decrypting. I want to download a Win 10 ISO from Microsoft and install it using my Win 8 key. No other steps required. Is that possible?

 

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.

Now that I have finally upgraded from Windows 8 to Windows 10 will my Windows 8 key work with a fresh install of Windows 10?
