Process Monitor for Debugging

The Process Monitor looks like a great tool to help in debugging issues and includes a bunch of features from a diverse set of sysinternal utilities such as RegMon, FileMon etc. I think this is the first tool offering to come out since the acquisition of and more importantly perhaps, Mark Russinovich (who has bunch of interesting posts about debugging issues). Looks like there is even a dedicated Sysinternals Blog at TechNet and if you are not familiar with the sysinternal family of tools there is a free Tour of the Sysinternals video available.
