Windows Management Instrumentation (winmgmt) Service Defaults in Windows XP

Provides a common interface and object model to access management information about operating system, devices, applications and services. If this service is stopped, most Windows-based software will not function properly. If this service is disabled, any services that explicitly depend on it will fail to start.

Default Behavior

Windows Management Instrumentation is a Win32 service. In Windows XP it is starting automatically along with the operating system.

If the Windows Management Instrumentation fails to load or initialize, Windows XP start up proceeds without error messages, but information about the failure is being written into Event Log.
