Launchy - application launcher for Windows, similar to Spotlight on OS X.

I've been looking for a tool similar to Spotlight on OS X that allows
you to start applications by just typing their name. Finally came upon
one - Launch @ http://www.launchy.net/

Just type Alt-Space to bring it up, then type the program name.

Much much better than screwing around with the Start Menu programs list.

(and yes, I know Spotlight does so much more than this)
