Default Behavior

Plug and Play is a Win32 service. In Windows 7 it is starting automatically on the operating system startup. Then the Plug and Play 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 Plug and Play 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 PlugPlay service is not running because of the error.

Dependencies

If Plug and Play is stopped, the following services cannot start:
