What’s CrossDeviceStreamingHost.exe (CrossDeviceStreamingHost)? Is it safe or a virus?

CrossDeviceStreamingHost.exe is a process developed by Microsoft Corporation that allows for seamless streaming and communication between different devices within a network.

This executable helps to facilitate the sharing of media, files, and other content across various devices such as computers, tablets, smartphones, and Xbox consoles. It enables users to easily access and stream content from one device to another, enhancing the interconnectivity and functionality of a multi-device ecosystem.

On Microsoft's official website they write "You can configure a cross-device app to associate your apps for Windows, iOS, Android, and the web so that the app on each platform can read and write user activities that are published by any app in the group.

For example, a user is finishing up a press release on her PC at work before dinner with friends. At the restaurant, she gets a notification from her boss about a typo that needs to be fixed asap. She opens the app on her Android phone and sees a card showing the press release she was editing earlier. She taps the card to open it so she can fix the release immediately and get back to her friends.

With this cross-device app configuration in place, the user's activity feed is synchronized across devices and platforms effortlessly so you can build experiences that help users pick up important tasks where they left off from any app surface."

In summary, it looks like Microsoft uses this .exe as part of their Cross Device system, to link different devices together where user data is always available through syncing, and streaming across all devices.
