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
