Unix utilities for Windows.

Continuing to re-configure my Windows XP box I installed the excellent set of Unix utilities from unxutils at SourceForge. One command line tool that is missing from unxutils is bash. After some digging around I found a standalone version of bash at www.steve.org.uk.

Microsoft has Windows Services for UNIX. The one time I installed this (a few years ago) the installer failed and left my machine in a broken state. The set of tools and services in the Microsoft package is comprehensive and so I would like to use it. However, I don't want to take the risk of breaking my machine again. Anyone know if the installation issues have been fixed?
