Microsoft has created a Windows App for iOS, iPadOS, macOS, Windows, and web browsers. The app essentially takes the previous Windows 365 app and turns it into a central hub for streaming a copy of Windows from a remote PC, Azure Virtual Desktop, Windows 365, Microsoft Dev Box, and Microsoft’s Remote Desktop Services. The Windows App is also limited to Microsoft’s range of business accounts, but there are signs it will be available to consumers, too. The sign-in prompt on the Windows App on Windows (yes that’s a mouthful) suggests you can access the app using a personal Microsoft Account, but this functionality doesn’t work right now.
