TaskInfo is a very good shareware utility that combine a process manager, list of open files, and more :

Among other things, you can use it to 'tune' coLinux so it runs with a lower priority, so heavy applications like Gentoo emerge don't impact normal Windows usage.
Similar program is Process Monitor by MIcrosoft workers Mark Russinovich and Bryce Cogswell.
