AppLocker advances the app control features and functionality of Software Restriction Policies. AppLocker contains new capabilities and extensions that allow you to create rules to allow or deny apps from running based on unique identities of files and to specify which users or groups can run those apps.
AppLocker helps you control which apps and files users can run. These include executable files, scripts, Windows Installer files, dynamic-link libraries (DLLs), packaged apps (aka: Microsoft Store apps), and packaged app installers.
AppLocker policies can only be configured on and applied to computers that are running on the supported versions and editions of the Windows operating system. You can configure AppLocker policies on any edition of Windows 10, but you can only manage (enforce) AppLocker on devices running Windows 10 Enterprise and Windows 10 Education.
You can export an AppLocker policy from a computer running any edition of Windows 10, and import the AppLocker Policy to any computer running Windows 10 Enterprise or Windows 10 Education.
Exporting and importing an AppLocker policy from a computer can be used as a way to backup an restore your AppLocker policy, or to apply it on another computer.
This tutorial will show you how to export (backup) and import (restore) AppLocker policy using an XML file in Windows 10 Enterprise and Windows 10 Education.
