I am using these system notifications to detect a power off or power on event for windows. Now I am trying to delay power off event and execute one function before that So how is that possible.

     [DllImport(@"User32", EntryPoint = "RegisterPowerSettingNotification",
          CallingConvention = CallingConvention.StdCall)]
     private static extern IntPtr RegisterPowerSettingNotification(
         IntPtr hRecipient,
         ref Guid PowerSettingGuid,
         Int32 Flags);

     [DllImport(@"User32", EntryPoint = "UnregisterPowerSettingNotification",
          CallingConvention = CallingConvention.StdCall)]
     private static extern bool UnregisterPowerSettingNotification(
         IntPtr handle);

    Maybe this can help: http://msdn.microsoft.com/en-us/library/windows/desktop/aa373208%28v=vs.85%29.aspx (`SetThreadExecutionState` function). Recommended by MSDN to use from `WM_POWERBROADCAST` message handler. – Alex F Oct 21 '14 at 07:00
