Windows App
Microsoft Windows App for macOS lets you securely connect from a Mac to remote Windows PCs, cloud PCs, and published apps.
What is Windows App?
Windows App is Microsoft's remote access client for macOS. It is used to connect a Mac to Windows resources such as Azure Virtual Desktop, Windows 365 Cloud PCs, Microsoft Dev Box environments, Remote Desktop Services, and individual remote PCs. On Mac, it effectively succeeds the older Microsoft Remote Desktop experience for many common use cases, which matches the legacy bundle ID com.microsoft.rdc.macos that users may still see in files or settings. Typical users encounter it in business, school, IT administration, and hybrid work setups where Windows apps or desktops must be accessed from a Mac. The app supports remote session features such as multiple displays, custom resolutions, device redirection, and account-based access to assigned work resources. It may also store connection definitions, credentials references, and workspace data locally so users can reconnect quickly. In most cases, it is a legitimate Microsoft app and not something harmful by itself.

Safety overview
Status: Safe
This is generally a legitimate Microsoft remote access application. The main privacy and security considerations are the remote systems it connects to, stored connection settings, and any credentials or corporate workspaces associated with it, rather than the app itself.
Recommendation: Keep it if you use remote Windows PCs, Azure Virtual Desktop, Windows 365, Dev Box, or other Microsoft-hosted Windows resources from your Mac. If you no longer use those services, removal is usually optional and mainly affects saved remote connections and local app data.
