Whether you’re an IT Pro or a developer, you’ll find
Sysinternals utilities to help you manage, troubleshoot and diagnose your
Windows systems and applications. If you have a question about a tool or how to

Sysinternals Live
Sysinternals Live is a service that enables you to execute
Sysinternals tools directly from the Web without hunting for and manually downloading
them. Simply enter a tool’s Sysinternals Live path into Windows Explorer or a
command prompt as http://live.sysinternals.com/<toolname> or
\\live.sysinternals.com\tools\<toolname>.
The Sysinternals Troubleshooting Utilities have been rolled
up into a single Suite of tools. This file contains the individual
