A few days back when I was going thru some malware solution article and security related stuff..I happened to check process explorer which is a part of Sysinternals Suite. Interestingly I got bunch of other utilities also from the same link.

For example -AutoRuns,BgInfo,Desktops,DebugView,DiskView,Process Explorer,etc.

For the complete list of the tools visit this link : http://technet.microsoft.com/en-us/sysinternals/bb545027.aspx

Moreover as we all know, Microsoft acquired Sysinternals in July, 2006.but here is the link about the great brain behind those tools. -Mark Russinovich. The Sysinternals Troubleshooting Utilities have been rolled up into a single Suite of tools. This file contains the individual troubleshooting tools and help files. It does not contain non-troubleshooting tools like the BSOD Screen Saver or NotMyFault.

Complete tool available for download (updated Sept 02, 2008 ): http://download.sysinternals.com/Files/SysinternalsSuite.zip
