Windows has it's own Remote Desktop app, and there's one in the Store [for whatever reason], and Microsoft's killing off the Store version on May 27, 2025.
All users are now urged to move from the Remote Desktop app to the Windows App if they want to continue using Windows 365, Azure Virtual Desktop, and Microsoft Dev Box. After May 27, 2025, access to those features will be cut, leaving users no option other than to switch.
