For Windows 10 Professional it is not possible to do this with GPO. So add in the GPO this to the register.

HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\ContentDeliveryManager

SilentInstalledAppsEnabled DWORD
0 = Disable
1 = Enable

I Also disabked PreInstalledAppsEnabled

Located HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\ContentDeliveryManager

PreInstalledAppsEnabled DWORD
0 = Disable
1 = Enable
