Helix, by Drew Fahey of e-fense, is a free live forensic live CD. It doesn’t touch the hard drive unless you tell it to. Helix also sports the sorts of tools you’d expect on a forensic CD. The CD provides distributable Windows binaries, including a Windows shell, that run within Windows. I downloaded Helix 1.4 (2004-07-04), burned it to CD and it started without incident on a Dell PowerEdge 750.”]
