Having a Live USB key is better than just using a Live CD because you can even save your data and install software. This feature is called persistence (available only on selected Linux).

I can't swear to it but I think Parted Magic has that capability.

ISO Recorder is a freeware tool which makes image writing available from the Windows desktop. Download and install ISO Recorder according to the instructions on their home page.

This is the simplest available method for writing disc images under Windows.
