.NET WinForms - How to listen to events for system LogOff, User Locked, Hibernate Started and System resumed?

Question:
I want to listen to events in my windows forms .NET application for the following system wide events :

Log Off Lock Windows Hibernate Started Sleep Started System Resumed

Are these possible?

Ans:

You need to look WMI (Windows media instrumentation). You would need to create event watchers for the above mentioned events.
