To switch from Home to Pro or Vice-Versa, this is another technique.
I recommend cloning the drive first so you have a backup. Run one of the following from an Admin Powershell or Terminal window (or make the Regedits manually). Then run Windows 10 or 11 ( https://go.microsoft.com/fwlink/?linkid=2171764 ) update, and the edition installed should be correct after the updates are finished. Home to Pro: Copy to Clipboard
Set-ItemProperty -Path "HKLM:\Software\Microsoft\Windows NT\CurrentVersion" -Name EditionID -Type String -Value Professional
Set-ItemProperty -Path "HKLM:\Software\Microsoft\Windows NT\CurrentVersion" -Name ProductName "Windows 10 Pro"
Set-ItemProperty -Path "HKLM:\Software\Microsoft\Windows NT\CurrentVersion" -Name CompositionEditionID -Value "Enterprise"
Pro to Home: Copy to Clipboard
Set-ItemProperty -Path "HKLM:\Software\Microsoft\Windows NT\CurrentVersion" -Name EditionID -Type String -Value Core
Set-ItemProperty -Path "HKLM:\Software\Microsoft\Windows NT\CurrentVersion" -Name ProductName -Value "Windows 10 Home"
Set-ItemProperty -Path "HKLM:\Software\Microsoft\Windows NT\CurrentVersion" -Name CompositionEditionID -Value "Core"
