User Profile Service (ProfSvc) Defaults in Windows 7

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 logon or logoff, applications may have problems getting to users' data, and components registered to receive profile event notifications will not receive them.

Default Behavior

User Profile Service is a Win32 service. In Windows 7 it is starting automatically on the operating system startup. Then the User Profile Service is running as LocalSystem in a shared process of svchost.exe. Other system components, such as drivers and services, may run in the same process. If User Profile Service 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 ProfSvc service is not running because of the error.


User Profile Service is unable to 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.

Restore Default Startup Configuration of 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 C:\Windows\system32 directory. If the file is removed or corrupted, read this article to restore its original version from Windows 7 installation media.
