This service is responsible for loading and unloading user profiles.

Default Behavior
User Profile Service is a Win32 service. In Windows 8 it is starting automatically during the operating system startup. Then the User Profile Service runs as LocalSystem in a process of svchost.exe, sharing it with other services. If User Profile Service fails to start, the error details are added to Windows 8 error log. When the operating system startup is complete, the user is being notified that the ProfSvc service hasn't been started.
Dependencies
User Profile Service can't start, if the Remote Procedure Call (RPC) service is disabled or not available.
If User Profile Service is disabled, the Application Information service will not be started and initialized.
