Default Behavior

Application Identity is a Win32 service. In Windows 10 it is starting only if the user, an application or another service starts it. When the Application Identity service is started, it is running as NT Authority\LocalService in a shared process of svchost.exe along with other services. If Application Identity fails to start, the failure details are being recorded into Event Log. Then Windows 10 will start up and notify the user that the AppIDSvc service has failed to start due to the error.

Dependencies

Application Identity cannot be started under any conditions, if the following services are disabled, deleted or working improperly:

While Application Identity is stopped, the Smartlocker Filter Driver service cannot be launched.

Restore Default Startup Configuration for Application Identity

Before you begin doing this, make sure that all the services on which Application Identity depends are configured by default and function properly. See the list of dependencies above.

1. Run the Command Prompt as an administrator.

2. Copy the command below, paste it into the command window and press ENTER:

sc config AppIDSvc start= demand

3. Close the command window and restart the computer.

The AppIDSvc service is using the appidsvc.dll file that is located in the %WinDir%\System32 folder. If the file is changed, damaged or deleted, you can restore its original version from Windows 10 installation media.
