Windows 11 Home to Pro upgrade

Want to upgrade 11 Home to 11 Pro. Tried download, but apparently files transferred were for 11 Enterprise. This will not activate; error is "invalid digital license or product key". This is on a new Surface. How to proceed?

Can withdraw/delete this. The suggestion to downgrade - listed below - with a 'fake' windows 10 key works.

 

windows 10 key

Thanks but I don't want to do any decrypting. I want to download a Win 10 ISO from Microsoft and install it using my Win 8 key. No other steps required. Is that possible?

 

Activate Windows 11 Pro with Key

I have recently bought a PC which has come with an unactivated Windows 11 Home Edition. I thought that I could use a Windows 11 Pro Key to install and activate a Windows 11 Pro Edition on the PC.

I have tried to enter the key in the "change product key" part but I get an error message telling me that it doesn't work. I am not very great with Computers so I dont know what to do next. The product key came with a disc that I can't use because my PC doesn't have a driver for those.

I was not able to insert a picture but it says "Der eingegebene Product Key funktioniert nicht. Überprüfen Sie den Product Key, und versuchen sie es noch einmal, oder geben Sie einen anderen Product Key ein. (0xc004f050)"
