Just got a notice that Windows Remote Desktop will end support May 27, 2025. Transition to Windows App?!

Thanks all!  Much to comfort me!  I will try some of these suggestions, including the Chrome option.  

Dave:
The Windows app is a replacement for the Windows Remote Desktop Client  that includes the same basic functionality to allow direct connections over your local network, but also allows for various cloud connectivity and mobile device management options (used by employers) as well.

The Windows Remote Desktop Client should continue to work, but will no longer be updated and may eventually be made incompatible with any updates to the host (your Mini PC) so moving to the Windows app would be advisable. However, other than a minor interface facelift you won’t lose any of the basic Remote Desktop functionality (you don’t even have to change anything on the host Mini OC) and there’s no requirement to use any of the cloud features. 

For now at least it’s essentially just a name change and new look. Microsoft could obviously make changes to the functionality in the future but in it’s current state there shouldn’t be anything to fret over.

I think my biggest concern for a move to the Windows App as a cloud thing is how it works in the absence of an internet connection.  Part of my fear is the unknown about how all this works.  Also, my past understanding of Cloud Applications/etc. is that these do not reside on the PC-in-hand, but in the cloud.  Initiation of said apps cause the PC to reach out to a server somewhere, download whatever part of the app is being called for, then it executes.  That buggers all this up if the computer is being used out in the field where there may be no access to the internet.  Its one thing if I control what applications I buy and put onto my computer, its a whole 'nuther matter if it is the operating system that works that way!

Having long ago built a nice home theater computer based on Windows Media Center, with tuners, etc. yielding a wonderful performing system, at a reasonable one-time cost, and untied to any subscription rip-off being sold by the local cable providers, etc., I learned my lesson of what happens when Microsoft suddenly decides to not support a functionality it once did.  Nothing like pulling the rug out from under customers!  I still have that computer with many saved videos stored.  But I long ago disconnected it from the internet so that my Windows update did not destroy it in the process of updating the operating system.  

I wish that for these small working PCs, that Microsoft would provide a check box that would essentially freeze the operating system permanently in a current working condition.  I really do not need to browse the web with what is essentially just a telescope/mount controller.
