Windows 10: Trouble changing the product key for windows 11 home activation

I recently acquired a new PC and the windows 11 home activation prefilled with my laptop's product key after I signed in with my Microsoft account. I purchased a new windows 11 license through the Microsoft online store so I have a genuine product key that should work. However whenever I try to change the key I get the error "It looks like the hardware on this device has changed. Make sure you're connected to the Internet and try again later. 0xc0ea00a"Currently I have my new PC linked to my Microsoft account, so it appears under the devices tab. Any help/advice would be greatly appreciated.

Product Key Reactivation

Hi

Thanks for your reply.

Reactivating Windows 11 after retrieving the motherboard key involves using the original product key or digital license associated with your system.

Here are the steps to reactivate Windows 11:

1. Open Settings:
   
   • Click on the Start button and select the gear icon to open "Settings."
     
2. Navigate to Update & Security:
   
   • In the Settings menu, click on "Update & Security."
     
3. Go to Activation:
   
   • In the left sidebar, select "Activation."
     
4. Enter Product Key:
   
   • If you have a product key, click on "Change product key" and enter the key when prompted.
     
5. Use Digital License:
   
   • If your Windows 11 was linked to your Microsoft account, you might see an option to troubleshoot and link your digital license. Click on this option and follow the prompts.
     
6. Restart Your Computer:
   
   • After entering the product key or linking your digital license, restart your computer.
     
7. Verification:
   
   • Go back to the Activation section in Settings to verify that Windows 11 is now activated.
     

 

Windows 10 product keys and activation - and the KMS angle

Changing the product key to the generic Windows 10 product key will reset activation to the standard retail channel for activation. It might just activate (if there was a previous digital license for Windows 10 for that computer established with Microsoft). Once Windows 10 is back on the retail activation channel, then more than likely changing the product key to the Windows 8 product key using the same method may work.

 

Windows won't activate a digital license but will with a product key?

If you plan on "transferring" a digital license from one computer to another using the activation troubleshooter and your Microsoft Account, then yes, start with the generic product key on the new computer. Actually, on a new install, you select the option for "I don't have a product key" and then after the install use the Activation Troubleshooter. Otherwise, if you are using a unique product key, either purchased or embedded in the firmware of the computer by the factory - let Windows 10/11 activate for the first time from that product key. AFTER it is activated, change the product key to the generic. One advantage to doing this is that if the original product key was OEM, changing it to the generic retail product key will also change the digital license type to retail and make it transferrable to another computer.
