IOnOffTransitionManager

  • Article

Enables the client to store the profiles in the IProfileCollection to the registry for boot tracing, but does not run the profiles. This behavior contrasts with that ofIControlManager, which runs the profile immediately. When the system boots, Event Tracing for Windows (ETW) reads the registry keys and enables providers for boot tracing accordingly. The library enables collection of PCW data by starting a task scheduler job configured to run on boot.
