User Profile Service (ProfSvc) Defaults in Windows 10

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.

Default Behavior

User Profile Service is a Win32 service. In Windows 10 it is starting automatically when the operating system starts. Then the User Profile Service is running as LocalSystem in a shared process of svchost.exe along with other services. If User Profile Service fails to start, the failure details are being recorded into Event Log. Then Windows 10 will start up and notify the user that the ProfSvc service has failed to start due to the error.

Dependencies

User Profile Service cannot be started under any conditions, if the Remote Procedure Call (RPC) service is disabled.

While User Profile Service is stopped, disabled or working incorrectly, the following services do not start:

Restore Default Startup Configuration for User Profile Service

Before you begin doing this, make sure that all the services on which User Profile Service 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 commands below, paste them into the command window and press ENTER:

sc config ProfSvc start= auto
sc start ProfSvc

3. Close the command window and restart the computer.

The ProfSvc service is using the profsvc.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.
