User Profile Service - Windows 8 Service
This service is responsible for loading and unloading user profiles. If this service is stopped or disabled, users will no longer be able to successfully sign in or sign out, apps might have problems getting to users' data, and components registered to receive profile event notifications won't receive them.
This service also exists in Windows 10, 11, 7 and Vista.

Windows 8 startup proceeds, but a message box is displayed informing you that the ProfSvc service has failed to start.

User Profile Service won't start, if the Remote Procedure Call (RPC) service is stopped or disabled.
If User Profile Service is stopped, the Application Information service fails to start and initialize.
