Windows 10: Free upgrade from windows 10 to 11 Needs new product key?

I upgraded from windows 10 to 11 home years ago using the free upgrade from Microsoft and I had no problems with the activation.Suddenly this week I'm being asked for a new product key I've tried restarting, resetting what I do I keep getting the0xC004F012 error and 0xc0000022 when troubleshooting from system activation. Did the free upgrade from Microsoft have a expiration date or something?

Cannot upgrade to Windows 10 - Unique Product Key situation

No... let me try again.

• Old computer is running Win7 Pro (SP1) with a Product key I have from a few years ago. The Product is activated already, but I do NOT use this computer at this point, so I didn't worry about using the Product key when moving to the new computer (see below).
  
• New computer is running Win10 Pro, with data and OS migrated from the Old computer, (same Product key as above), then Upgraded to Win10 (without getting a new Product Key).

What I am trying to do now...

• I want to upgrade the OLD computer (Win7 Pro) to Windows 10... using a new Product Key I just purchased.
• I have tried to do this internally, and also using the ISO burned to a thumb drive. But it does not want to work.
• Steps:
  • Start from USB drive.
  • Enter New Product Key (or click "I don't have one").
  • Install initiates and then tells me to restart from Windows and then open the installer again to continue.
    • At this point, I actually need to Quit the installation to restart the machine.
  • When restarted, I go to the USB drive and restart/resume the installation process.
  • I have tried to download and not to download updates, but when the installation fails, I see the message, "Something happened" and "Setup has failed to validate the product key".
  • NOTE This happens if I enter the NEW Windows 10 Product Key, or if I skip that step (which I assume means that it will use the old Windows 7 Key for the upgrade).

 

windows 10 key

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?

 

I built a new computer running windows 11 home. Can I transfer my product key from my old windows 10 Pro?

How can I transfer my license to my new PC? I have verified it's a retail copy but I can't activate the product key and the upgrading hardware step doesn't list my new PC.

Do I need Windows 11 Pro or should the 10 Pro key automatically upgrade me?

How do I do this?
