AppLocker is an enhancement of the Software Restriction Policies. With AppLocker you can add more capabilities and extensions to create new rules and allow or deny apps based on more specific file identities.

Using AppLocker, you can control many different types of applications, define rules based on attributes, assign rules to individual users or groups, create exception rules, import and export the rules you change, use Windows PowerShell cmdlets for creating and managing your AppLocker rules.
