New Power Management Features : Windows Server 2008 R2

The Windows operating system features built-in infrastructure services (Service Control Manager and Task Scheduler) that help manage background processes. Windows takes advantage of the built-in services to provide system management, device management, and
system maintenance functionality.
Significant improvements have been made to this infrastructure for Windows 7 and Windows Server 2008 R2. Developers can use these improvements to develop Windows services that are efficient and that contribute to the overall system performance and security.
Hi.
We have recently created "Service Trigger Editor", a free GUI utility for adding/editing/viewing Service Triggers:

For those who want to explore Trigger-Start services, it is a good alternative to using the SC.exe command (or writing your own code).
