Windows 7, as some have already noted, offers a number of powerful command line tools. Ironically, this type of thing has been available for Mac OSX (BSD driven OS) and Linux/UNIX systems for years.
However, Microsoft seems to have learned that power users prefer powerful access to their computer OS, and I wanted to write about another useful command.
powercfg -ENERGY
This command allows you to get details about your system's power management. The details are quite thorough and in today's business world of Green is better, this type of utility is refreshingly useful.
Use this command by starting with the Start button -> All Programs -> Accessories and open Command Prompt. From there type:
powercfg -ENERGY
Enjoy!
