Installing and configuring Windows App on Thin Client environments

I am seeking technical guidance on accessing the new Windows App from Thin Client environments, following the end of support for the Microsoft Remote Desktop client (27 March 2026).

Current Environment

• End-user devices: Thin Clients used by customers
• Thin Client OS types in use:
  • Windows 10 IoT Enterprise, and/or
  • Thin Clients running custom NComputing firmware
• Backend environment:
  • Windows Server–based environment hosting a line-of-business application (accessed via RDP / RDS)

Current Access Method

• Users currently connect using the Microsoft Remote Desktop (RDP) client, accessing either:
  • A full desktop session, or
  • Published RemoteApps via RDS
• This setup is functioning today but is impacted due to Remote Desktop app end of support.

Issue / Challenge

• Microsoft is recommending migration from Remote Desktop app to the Windows App.
• However, during evaluation, we are facing blocking limitations on Thin Client devices, specifically:
  • Windows App is not supported / cannot be installed on:
    • Windows 10 IoT–based thin clients, and
    • Thin clients running custom NComputing firmware
  • These devices have:
    • Limited hardware resources
    • Restricted OS / firmware‑level constraints
    • No support for installing modern Store / Windows App packages
• As a result, users cannot access the environment using Windows App, creating a risk of service disruption.

What We Need :

We request Microsoft’s official technical and product guidance on the following:

1. Confirmation
   • Is the Windows App officially supported on:
     • Windows 10 IoT Enterprise?
     • NComputing or other firmware‑based thin clients?
2. Alternative Supported Options
   • Are there supported alternatives for thin clients after Remote Desktop app end of support:
     • Web-based access?
     • Legacy RDP components still supported for Windows Server?
     • Specific RDS client versions approved for IoT devices?
3. Best‑Practice Architecture
   • Recommended Microsoft‑supported architecture for:
     • Thin client environments
     • RDS / RemoteApp access
     • Scenarios where Windows App installation is not possible
4. Risk & Compliance Clarification
   • Guidance on continued use of RDP clients in end-of-support but still operational mode, and
   • Associated security or compliance implications, if temporary continuation is required.

This information is critical to ensure business continuity for customers who cannot upgrade thin client hardware or firmware immediately.
