How to Use AppLocker to Block Microsoft Store Apps from Running in Windows 10

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, and packaged app installers.

Packaged apps are also known as Universal Windows Platform (UWP) apps from the Microsoft Store or already included with Windows 10.

Here's How:

1. Open an elevated command prompt.

2. Copy and paste the command below into the elevated command prompt, press Enter, and close the elevated command prompt when it has finished. (see screenshot below)

This command is to make sure the Application Identity service is enabled, set to Automatic, and running. AppLocker cannot enforce rules if this service is not running.
