How to reactivate windows 11 after a hardware change

I've changed drives, motherboard, and CPU and now cannot activate Windows 11. The new drive was cloned so it looks like the old drive and boots int Windows fine. I've tried all the Microsoft suggestions and it always comes back saying, "We can’t find any devices linked to your Microsoft account that can be used for reactivating the device you’re using right now". When I look at my account I see the old device and it has the same ID as I see in Settings. I've tried activating numerous times and am stumped.

Please try to check the type of license installed on your system.

  1. Open administrative Command Prompt.
  2. Type slmgr /dlv and press Enter key.
  3. Note the Product Key Channel section Windows Script Host box:
  • If it mentions OEM <method>, you’ve OEM license installed.
  • If it says Retail, you’ve retail license installed.
  • If it mentions GVLK, VOLUME_<method> then you’ve volume license installed. Note that GVLK stands for Generic Volume License Key.

So if you've OEM license, it is lost due to motherboard replacement. Changing motherboard requires new license.

If you've Retail license, you reactivate it again with its product key.

Hi,

If it was a custom-built PC, the license might have been a physical 25-digit key, or you might have purchased a digital license.

You can check your Microsoft account for any Windows 10 purchase at the link below:

If the system was upgraded from Windows 7 or 8 to Windows 10, then it is an OEM license, and that license cannot be reused.

If you cannot find a record of the purchase and activation fails after a hardware change, it was likely a physical 25-digit license or an OEM license.

Thanks.

Hi,

Did you purchase the Windows license separately, or did it come with the computer?

We need to verify the type of license you have—whether it is Retail or OEM.

If it is an OEM license, it is tied to the hardware (specifically the motherboard) and cannot be transferred; therefore, if you have changed the hardware and hold this type of license, you would need to purchase a new one.

Thanks

    Thanks all. Not sure where the license came from. CMD said it was retail. I had details in One Note, but that license didn't work. Wound up buying one and now it's activated.

    So I guess if I ever rebuild again I'll be going through the same stuff again.

    I'm not really sure because I've been using it for years, the PC was built by me, not purchased. It might have been an upgrade from Windows 10, just cannot remember. I rebuilt my it less than 2 years ago and it reactivated easily when I first got into Windows 11.
