They have released an update of Procmon

Announcing Process Monitor v1.0

We're excited to announce the release of Process Monitor, a system monitoring tool that not only replaces Regmon and Filemon by including file system and registry monitoring, but adds process, thread, and DLL monitoring as well as advanced filtering, event information, and basic data mining capabilities.

   

I highly recommend it!
