This Windows app is limited to Microsoft work and school accounts, as it’s primarily designed for existing users of Remote Desktop clients for Windows and other operating systems to move to. Microsoft has had similar apps for connecting to PCs remotely in Windows for decades, including the Remote Desktop Connection app that still ships as part of Windows 11. These apps, including the new Windows one, are useful for connecting to work PCs from a personal laptop or PC.
There are no signs that Microsoft plans to support consumer accounts with its new Windows app, though. Last year, it was revealed that Microsoft has a long-term goal of moving Windows fully to the cloud to “enable improved AI-powered services and full roaming of people’s digital experience.”
