As Moondoggy stated, they do not have the key that you reference, therefore can't follow this direction. " Specifically the MicrosoftEdge key in HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\MicrosoftEdge\Main." I, too am having this problem - the key you reference doesn't exist. Please help with an alternative method. I'm using Windows 10 Home and do not have access to gpedit, either.
