Recover original windows 11 version using product key

Hello,

I have just bought a new laptop, and it has its own product key for windows 11. However, I upgraded the windows version to windows 11 pro. Now, the product key is no longer working, and I want to recover the original windows 11 version where the product key is licensed.

Thank you,

 

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.
     

 

Upgrading Windows 11 Home using Windows 8.1 Pro Product Key

Hello- I just bought a laptop which is preinstalled with Windows 11 Home. I have an old PC with Windows 8.1 Pro which is too old to use. I would like to upgrade the preinstalled Windows 11 Home using my old Windows 8.1 Pro Product Key. Since Win11 is already activated on my new laptop, I do not have the option to troubleshoot and Click "I changed changed hardware on this device recently." I cannot find a phone number to call MS support. Any suggestions? Thanks
