Windows 10: Can i Restore Preinstalled window

Himy friend bought a new laptop that come with preinstalled window 11.He wanted to downgrade to win10. So he sent it to the so called service in my small town..I checked win license with cmd slmgr /dlv. That seems the service shop deleted the preinstalled win11 and installed Win10Pro using KMS.This new win10Pro is not official.Can he get his preinstalled win11 key? Or how to get back to official window

Restoring Windows 10 Image using Macrium Reflect


In addition to the above. Here's my suggestion in step by step.
I assume you have Macrium Installed in your current HD and already made a backup copy.

1. Connect your new HD via USB port and boot up.
2. Run Macrium, click on Restore tab then select the Backup Image that you made to restore
3. click on "select a different target disk" then select your new HD as destination
   
   
   
4. Proceed to restore then Shutdown and disconnect the old HD and replace with the new HD
5. Boot up with your new HD.
