Hi,
can you please try taking the ownership of one of those registry key and then run the cmdlet again? What happens?
Can you please also test with the "-Credential" parameter, which will allow you to enter your credentials. Something like:
Set-ItemProperty –path “HKCU:\Console” –name QuickEdit –value 1 -Credential Get-Credential
Can you please also take a look here and see if you find something helpful:
