Default Behavior

Application Identity is a Win32 service. In Windows 7 it won't be started if the user doesn't start it. When the Application Identity service is started, it is running as NT Authority\LocalService in a shared process of svchost.exe. Other system components, such as drivers and services, may run in the same process. If Application Identity fails to start, Windows 7 attempts to write the failure details into Event Log. Then Windows 7 startup should proceed and the user should be notified that the AppIDSvc service is not running because of the error.

Dependencies

Application Identity is unable to start, if at least one of the following services is stopped or disabled:

2. Save the Win7_AppIDSvc_Service_Startup.cmd file to a local storage device.

3. Run the saved file as an administrator.

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 7 installation media.
