I am so tragically unhip...I know! Anyway I thought this was remarkably useful, a simple way to download the Sysinternals tools without having to trudge through a webpage...a retweet from Jon (no relation) Galloway. Zoomit is worth the price of admission alone for presenters!
UPDATE: What I didn't know is that in Win2008 / Vista you can do this:
\\live.sysinternals.com\tools\procexp.exe and run the tool directly from the web...now that's useful!
