For anybody interested in the Sytem Internals Tools, I recommend to download and watch this excellent video by Mark Russinovich and David Solomon that you find here: ( David Solomon Expert Seminars ). Go to the link where the arrow points:
The total presentation is about 50 minutes and the download file for that is appr. 100MBs. The first 10 minutes are mainly about the history of the tools and may seem a little boring, but once they go into medias res, it is really interesting.
On this site: ( Windows Sysinternals: Documentation, downloads and additional resources ), you can find a lot of additional information about the individual tools.
You can also get the Expert Seminars by David Solomon from the first link. But they are a little pricey.
