Modern Windows setups with multiple monitors at different scale factors (100 %, 125 %, 150 %, …) expose a hard Win32 limitation the moment you embed a foreign process window into your own application via SetParent. Windows simply does not forward WM_DPICHANGED across process boundaries.

This article documents the investigation and the two different solutions NETworkManager uses for its embedded PowerShell (a console host process) and PuTTY (a GUI process) tabs — together with the complete, relevant C# source code.

NETworkManager now supports system-wide policies, giving administrators centralized control over application settings across all users on a machine. This feature is available since the pre-release version 2026.02.19.0 and can now be tested.

The latest release of NETworkManager (version 2025.10.18.0) introduces major enhancements to the light theme, improving both readability and overall user experience.

In this version, the code that handles theming has been completely rewritten, providing granular control over colors and styles. This allows users to fine-tune the light and dark themes independently, ensuring better contrast, visibility, and accessibility across the interface.

The light theme has already received several improvements to enhance readability, and more adjustments are planned for future releases based on user feedback. So please don’t hesitate to share your thoughts on the GitHub issue tracker.

NETworkManager 2025.10.18.0 brings a streamlined approach to profile management with the introduction of Tags and Filtering.

You can now add or remove tags directly within each profile, making it effortless to organize and quickly locate your hosts and networks.

NETworkManager 2025.8.10.0 introduced a new feature, the Hosts File Editor. You can now easily manage and edit your system's hosts file in a user-friendly interface.

As a sysadmin or developer, you often need to modify the hosts file in order to override DNS settings for specific domains, redirect traffic, or test websites locally.

Starting with NETworkManager version 2024.5.24.0, the binaries and the installer are now signed with a code signing certificate.

Welcome to the new NETworkManager website, blog and documentation.

It's built with Docusaurus, a static website generator, and hosted on GitHub Pages.
