Start++ is an enhancement for the Start Menu in Windows Vista. It also extends the Run box and the command-line with customizable commands. For example, typing "w Windows Vista" will take you to the Windows Vista page on Wikipedia.

Typing "sudo" followed by a command will run that command with elevated (admin) privileges. Super handy from the command-line as well.

Advanced functions can work with search results, powered by Windows Vista's integrated desktop search engine. For example, typing "play radiohead" will find all music that matches the query "radiohead", compile the results into a .M3U file, and launch it in your favourite media player (actually, it only uses Windows Media Player for the moment, but that will change soon).

Some commands will trigger custom UI in the Start Menu in response to your commands.
