Changing product key on Windows 11 Home to Windows 11 PRO error.

[JazzFlute]

First time I've received an error doing this trying to upgrade a new laptop with Windows 11 Home installed to my OVS Windows 11 PRO MAK Key.  I receive the generic error in Pic, also tried other keys I have and all result in the same error.  Have to create a normal Microsoft account to log this with them rather than my school account as its classed as home support apparently.  Anyone had this problem too and if yes how did you solve it before I do more troubleshooting.

Try fully removing and deactivating the original key maybe as I dont know if the OVS key is an upgrade key.

• You can click Start, type cmd, right-click Command Prompt and select Run as administrator.
• Type the command wmic path SoftwareLicensingService get OA3xOriginalProductKey and press Enter to find your product key. You can take down the product key if you want to use it to activate another computer.
• Next, you can type the command: slmgr.vbs /upk. Press Enter to execute the command to uninstall the Windows 10/11 product key. You will see a message saying “Uninstalled product key successfully”.
• Then you type the command slmgr /cpky command and press Enter. It will eliminate the Windows 10/11 product key from the Windows registry.

Thanks, just tried that but still receive the same error and tried other Windows 11 keys, Enterprise, Education etc. and still receive the error.  I reactivated it for now with the Home Key and will investigate further on Monday.

I use the ipk command, instead of the /copy i.e. 

 

slmgr /ipk XXXXX-XXXXX-XXXXX-XXXXX-XXXXX

 

And then activate with

slmgr /ato

Solved: changed product key normally through Settings>Activation>Change Product Key and Used a Windows 11 Education Key (not Windows 11 Education N as this didnt work) then changed Producxt Key again to Windows 11 Pro and worked fine.
