The best Sysinternals tools for Windows that you should know.

The Sysinternals toolset is a valuable resource for Windows users seeking to enhance their experience in managing the operating system. These tools, developed by Microsoft, allow users to diagnose problems, optimize performance, and gain detailed insights into their computer's operation. Below, we will explore some of the most notable tools that every Windows user should consider.

Process Explorer: An advanced process manager

Process Explorer is one of the most popular tools in Sysinternals. This program provides a more detailed view of the running processes on your system compared to the standard Windows Task Manager. With Process Explorer, you can see which files and registry keys are open by each process, making it easier to identify problems and effectively manage system resources.

Autoruns: Full control over program startup

The Autoruns tool allows users to monitor and manage the programs that start automatically with Windows. Through this utility, it is possible to disable or delete unnecessary entries, which can speed up the system boot time and improve overall performance. Autoruns provides detailed information about the programs that run at startup, helping to keep the system free of unwanted software.

Process Monitor: Activity logging and analysis

Process Monitor is a tool that combines the functionalities of two previous programs, Filemon and Regmon. This program allows real-time monitoring of file systems and registry activity, providing a level of detail that can be extremely useful for administrators and those looking to troubleshoot specific issues on their system. You can filter events and gain insights into what happened when a program crashed.

Disk2vhd: Virtualize your hard drive

Disk2vhd is a tool that allows users to create disk images of their physical drives and convert them into VHD files. This is especially useful for those looking to migrate to virtual environments without losing data or configurations. The utility is easy to use and simplifies the virtualisation process, allowing for a smooth transition to platforms like Hyper-V.

TCPView: Network connection monitoring

TCPView provides a graphical interface that displays all TCP and UDP connections on your system. This tool is essential for those who wish to monitor network activity and can be particularly useful for detecting unwanted or potentially malicious connections. With TCPView, users can terminate connections directly from the interface, providing effective control over network security.

PsExec: Remote process execution

PsExec is a tool that allows you to execute processes on remote systems via the command line. This can be invaluable for system administrators managing multiple devices. PsExec facilitates the execution of programs without the need for a graphical interface, optimizing time and resources when working in enterprise environments.

Sysinternals Suite: A complete set

It is important to highlight that all of these tools are available as part of the Sysinternals Suite, which offers a comprehensive collection of utilities in a single package. This allows users to easily access all the necessary tools for system diagnosis and optimization.


In summary, the Sysinternals toolset is indispensable for anyone looking to manage and optimize their Windows system. From process monitoring to disk virtualization, these utilities provide functionalities that can make a significant difference in your computer's performance and security.
