Windows Application control AppLocker

AppLocker is supported on systems running Windows 8.1. Software Restriction Policies (SRP) is supported on systems running Windows Vista or earlier. You can continue to use SRP for application control on your pre-Windows 7 computers, but use AppLocker for computers running Windows Server 2008 R2, Windows 7 and later. It's recommended that you author AppLocker and SRP rules in separate GPOs and target the GPO with SRP policies to systems running Windows Vista or earlier. When both SRP and AppLocker policies are applied to computers running Windows Server 2008 R2, Windows 7 and later, the SRP policies are ignored.
