Configure the Application Identity Service


Updated: May 2, 2012

Applies To: Windows 8.1, Windows Server 2012 R2, Windows Server 2012, Windows 8

This topic shows how to configure the Application Identity service to start automatically or manually in Windows Server 2012 and Windows 8.

The Application Identity service determines and verifies the identity of an application. Stopping this service will prevent AppLocker policies from being enforced.


When using Group Policy, you must configure it to start automatically in at least one Group Policy Object (GPO) that applies AppLocker rules. This is because AppLocker uses this service to verify the attributes of a file.

To start the Application Identity service automatically using Group Policy

  1. On the Start screen, type gpmc.msc to open the Group Policy Management Console (GPMC).

  2. Locate the GPO to edit, right-click the GPO, and click Edit.

  3. In the console tree under Computer Configuration\Windows Settings\Security Settings, click System Services.

  4. In the details pane, double-click Application Identity.

  5. In Application Identity Properties, configure the service to start automatically.

Membership in the local Administrators group, or equivalent, is the minimum required to complete this procedure.

To start the Application Identity service manually

  1. Right-click the taskbar, and click Start Task Manager.

  2. Click the Services tab, right-click AppIDSvc, and then click Start Service.

  3. Verify that the status for the Application Identity service is Running.
