Windows – How to run multiple instances of the new Remote Desktop client in Windows 10

How can I run multiple instances of the new RDP client on Windows 10?

According to the following statement.

"Windows Store apps are single instance. Windows allows only one instance of a Windows Store app to run at a time on the system.".

However, UWP applications support multiple views, but every view is a single instance of that application, but the UWP Remote Desktop application does not support multiple views. This means you cannot run multiple instances of the UWP remote desktop application, because it is not possible, to run multiple instances of UWP applications.

Is there an /allowMultiple switch or something I can set?

You cannot send an argument like /allowMultiple to an Universal Windows Platform application at this time.

UWP/store apps use no multiinstance, but use multi-view style. (Edge is an exception, maybe...)

In multi-view, the instance is same but each windows' 'Views' are running on each threads.

Although the the Stackoverflow answer goes on to indicate the following it does not apply to the UWP Remote Desktop application you are asking about. You can run multiple instances of the Win32 desktop variate of the Remote Desktop client (mstsc.exe) if you want.

As of build2017 presentations, it seems that Microsoft have a plan to extend their UWP App model to allow the real "Multi Instance" by their future Update of Windows. But the details are not available yet.
