Various rules can be created in the AppLocker. For example, create a rule for a file path.

- The "Editor for local group guidelines" opens. Select "Computer Configuration" -> "Windows Settings" -> "Security Settings" -> "Application Control Policies" -> "AppLocker".
- "Executable rules" prevent certain programs from starting, for example. Under "Windows Installer Rules" you can create rules regarding installations. Right-click on "Executable rules" and select "Create new rule".
- Under "Preparation", click "Next". In the next field, select "Deny". You can specify a specific group here or leave "Everyone".
- For example, select "Path" to lock a special file path. Find the path you want to block. Finally, click Create.
- Now open the command prompt. To do this, click the Windows start icon again and type "cmd.exe". In the opened window, type "gpupdate.exe" to renew the computer guidelines.
