Use Remote Desktop Connection or universal Remote Desktop client instead of RDMan in Windows 10
Virtualization and remote desktops are an important part of your infrastructure and work. And, we recommend that you use Windows built-in Remote Desktop Connection (%windir%\system32\mstsc.exe) or universal Remote Desktop client instead of Remote Desktop Connection Manager (RDCMan).
Applies to: Windows 10 - all editions

We're increasing our investments in virtualization and remote desktops, such as Azure Virtual Desktop and RDS on Microsoft Azure.
RDCMan is a client that is widely used to manage multiple remote desktop connections because it's a convenient option. However, RDCMan has not kept pace with the level of advanced technology that we're pursuing.
Instead, we have two great supported client options: Remote Desktop Connection and Universal Client for Windows 10. These clients offer increased security, and they are a key part of our engineering roadmap moving forward. In the future, you can expect even more capabilities, such as the ability to better manage multiple connections.
