SysInternals Utilities are a set of tools that help you troubleshoot and diagnose Windows systems and applications. Microsoft has gathered all the programs in one complete suite of power tools. Even so you can still download each program separately at Microsoft TechNet ( the SysInternals suite is the first item in the list ).
Users that already work with this tools will say, what's the point of this post? Well, SysInternals have launched a beta service, SysInternals Live, that lets you execute any SysInternals tool directly from the web. Like they say:
"Simply enter a tool’s Sysinternals Live path into Windows Explorer or a command prompt as \\live.sysinternals.com\tools\
or view the entire Sysinternals Live tools directory in a browser at http://live.sysinternals.com"
