The new tool from Sysinternals is released

Sysinternals / Microsoft have finally released Process Monitor which has the functionallity from the old Filemon and Regmon and adds a lot of nice features.
Perhaps the best improvement is non-destructive filters. So you can play around testing different filter settings, whithout destroying the log.
I just made a quick test, but it was nice. What are your system doing? Run process monitor, and it shows all registry and file activity...
