windows 11 home key not working after trying to upgrade for windows 11 pro

my laptop came with preinstalled windows 11 home activated then my brother took my laptop as he said to play games then he returned it to me when the laptop was restarting and showing that there's updates going when the laptop finished restarting he opened the activation statues of windows showing that it is an windows 11 pro but it wasn't activated and there's an error i ran the troubleshooter to fix it and it didn't work then i heard about showkeyplus to know my original windows 11 home key that came with my laptop to revert to it after my brother missed up with the windows 11 pro thing and when i enter the key of my windows 11 home that called OEM key windows says that the product key i entered didn't work, check the product key and try again or try a different key and i'm not willing to pay for another key because of my brother mistake is there anyway i can reactivate windows with the original windows 11 home key it came with?

 

Windows 11 Home Key But Windows 11 Pro Version

I purchased Windows 11 Home directly from Microsoft thinking that it'd work with Mac Parallels virtual environment. However, Parallels only seems to work with Windows 11 Pro as I have the M1 mac (ARM chip).

I am left with Windows 11 Pro version to be activated and Windows 11 Home key. How do I pay the difference and get the Windows 11 Pro key, so I can activate my Windows 11 Pro version in Parallels?

 

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?
