PowerModes in Microsoft.Win32

• Resume The operating system is about to resume from a suspended state.
• StatusChange A power mode status notification event has been raised by the operating system. This might indicate a weak or charging battery, a transition between AC power and battery, or another change in the status of the system power supply.
• Suspend The operating system is about to be suspended.

Microsoft.Win32 Namespace

The Microsoft. Win32 namespace provides two types of classes: those that handle events raised by the operating system and those that manipulate the system registry.

SystemEvent Class

Provides access to system event notifications. This class cannot be inherited.

• DisplaySettingsChanged Event
• DisplaySettingsChanging Event
• EventsThreadShutdown Event
• InstalledFontsChanged Event
• LowMemory Event
• PaletteChanged Event
• PowerModeChanged Event
• SessionEnded Event
• SessionEnding Event
• SessionSwitch Event
• TimeChanged Event
• TimerElapsed Event
• UserPreferenceChanged Event
• UserPreferenceChanging Event

Expose Keys in Registry

CurrentUser
Stores information about user preferences.
LocalMachine
Stores configuration information for the local machine.
ClassesRoot
Stores information about types (and classes) and their properties.
Users
Stores information about the default user configuration.
PerformanceData
Stores performance information for software components.
CurrentConfig
Stores non-user-specific hardware information.
DynData
Stores dynamic data.
