From Wednesday's TechNet Flash newsletter, Sysinternals (now a wholly-owned subsidiary of Microsoft) released three updates to their free tool suite:

Process Monitor v1.1, an advanced monitoring tool for Windows that shows real-time file system, registry, and process/thread activity. It combines the features of two earlier Sysinternals utilities, Filemon and Regmon, and adds an extensive list of new enhancements.

AccessChk v3.0, a security utility that shows you the methods that users have to gain access to files, registry keys, and services. The update adds support for processes, including display of their Windows Vista object and running integrity levels.

PSExec v1.80, a lightweight Telnet replacement that lets you execute processes on other systems. This update enhances the -i option to allow process launch in a specific session; on Windows Vista, the -l switch runs a process with low integrity.

If you go to the web site at http://www.microsoft.com/technet/sysinternals/default.mspx you'll also see a fourth tool update:

BgInfo v4.10, has been updated to correctly report versions of IE 7, remove extraneous network adapter info that appears under Vista, and improve text readability when overlaying on a background image.
