In the past I have talked about some great utilities that are available from Sysinternals that you could download. I have also talked about how Microsoft recently purchased the site in July 2006, and hired the authors (Mark Russinovich and Bryce Cogswell) of these tools. If you now go to the Sysinternals site, you will now be redirected to the Microsoft version of it.
Microsoft is continuing the Sysinternals legacy of utilities by keeping them available for download on their site. They have also rolled them up into a single suite, this suite contains all the individual tools and help files in one file (8MB in size).
