Microsoft has a 30 day trial version of the ERD Commander, a.k.a. Microsoft Diagnostics and Recovery Toolkit version 5.0. This might come in handy if you are in a pinch to fix a dead PC.
(5/3/09) Update: Microsoft removed the link, and due to other websites linking to a copy on my website, I removed mine as well.
