The updated RDCMan fixes the previous critical vulnerability. Microsoft took RDCMan off the market in 2020 because of critical security flaws, but the tool is back as part of the Sysinternals Suite.

RDCMan helps these users by consolidating multiple RDP connections into a single window, thus reducing desktop clutter. This includes system administrators, server lab managers, developers and testers. The tool is especially useful for individuals who work with groups of computers or large server farms where regular access to each machine is required. Using RDCMan, system administrators can supervise multiple RDP connections in a single window, use different RDP settings for separate servers or groups, and save user credentials, enabling automatic authentication on RDP and remote desktop service servers. It was created by Julian Burger, a developer on the Windows Live Experiences team to improve the management of multiple remote desktop protocol connections. Remote Desktop Connection Manager (RDCMan) is a free Microsoft tool that enables IT administrators to organize, group and control multiple remote desktop connections.
