Turn on UAC for built-in Admin Windows 10
Built in Administrator cannot run MS Store and Edge on Windows 10
If you login to a Windows 10 machine using built in Administrator nothing happens when you click Store or Edge.
This is because all Apps require UAC to be on and for the administrator account UAC is disabled.
A simple reg key needs to be switched and the computer rebooted:
reg add HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System /v FilterAdministratorToken /t REG_DWORD /d 1 /f
To turn off UAC again just replace the 1 with 0.
