Take control of your system with Windows Sysinternals

I recently purchased a Lenovo Thinkpad T61 (sorry Dell) and after performing a clean install of Windows XP SP3 (sorry Vista), as well as a full image backup with DriveImage XML (sorry Norton), I decided to search for those tools that will help me take a deeper control of my system and avoid chaos in the long run.  If you’re a Linux user, you might not know what I’m talking about.

Windows Sysinternals is Microsoft’s solution for Windows users to download advanced system utilities and technical information for free.  I don’t know about you, but when I see those four word (’advanced‘, ‘system‘, ‘utilities‘ and ‘free‘) in the same sentence, an interrupt gets triggered in my brain.  Seriously, these tools are a great asset for any Windows developers’ toolbox as some of the tools help in pinpointing memory usage information, manage processes and threads, etc.  In case you weren’t aware, Visual Studio doesn’t always ship with all the tools you might need.

As quoted in Windows Systinternals‘ home page:

The Sysinternals web site was created in 1996 by Mark Russinovich and Bryce Cogswell to host their advanced system utilities and technical information. Microsoft acquired Sysinternals in July, 2006. 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.

Windows Sysinternals utilities are grouped into the following six groups:

  1. File and Disk Utilities: Utilities for viewing and monitoring file and disk access and usage.
  2. Networking Utilities: Networking tools that range from connection monitors to resource security analyzers.
  3. Process Utilities: Utilities for looking under the hood to see what processes are doing and the resources they are consuming.
  4. Security Utilities: Security configuration and management utilities, including rootkit and spyware hunting programs.
  5. System Information: Utilities for looking at system resource usage and configuration.
  6. Miscellaneous Utilities: A collection of diverse utilities that includes a screen saver, presentation aid, and debugging tool.

Here is a complete list of the tools being offered by Windows Sysinternals for each group as well as their description (you can find all these categories here).
