Microsoft supports device redirection for peripherals like webcams, storage devices, and printers, as well as configurable display resolutions and scaling. These features are accessible through its Windows App. The preview version of the Windows App isn’t currently available for Android, though.
The Windows App is likewise restricted to business accounts offered by Microsoft, however, there are hints that individuals will also be able to access it. The sign-in prompt on the Windows App on Windows suggests you can access the app using a personal Microsoft Account, but this functionality doesn’t work yet.
A specialized "Windows App" is an odd branding choice, but it might be an indication that Microsoft is taking steps toward their larger goal of moving Windows entirely to the cloud.
