I recently installed Remote Desktop Manager on Windows 10 v1703 which unfortunately stole the file associations for .RDP file types. I want to reset this back to the default MSTSC which it has historically been.
When I access the "Default apps" screen the reset button only resets the Browser/Email and other items on the home page. Going into "Choose default apps by file type" I can see the entry for RDP but the only options for association are "Remote Desktop Manager" and "Look for an app in the store". Going into "Set defaults by app" shows that Windows 10 does not have an entry for MSTSC.
Uninstalling Remote Desktop Manager removes the association, but does not restore it to the previous value. The only option present is now to choose an app from the store.
Is there an easy way to reset the association or choose a random application from outside the pick list?
