I love using QuickSilver on my Mac, and finally I ran across the PC equivalent. It’s called Launchy and it works great!

This is what Launchy looks like
I have it configured to launch when I press ctrl-space. Just like QuickSilver, all you have to do is start typing and it finds the app you want to run. This is so much easier and faster than browsing folders or even placing icons on the Quick Launch Bar.
Check it out. So far I’m loving it.

I tried it before, but could never get used to it.
Although doesn’t the Vista / Win7 start menu have something like that for finding apps?
