Nothing is more exciting than new apps that do get installed automatically on your devices, right? That’s probably Microsoft’s official argument for starting to force-install new Microsoft 365 companion apps on Windows 11 devices from next month onward.
Microsoft confirmed the decision to Microsoft 365 administrators, but it has not informed regular customers of its Microsoft 365 service about it to my knowledge.
Here is what is going to happen: Starting in “early October 2025”, Microsoft will install the Companion apps People, Files, and Calendar on any Windows 11 device, provided that Microsoft 365 desktop client apps are installed.
Wonder what those do?
- People app: Extends search functionality for contacts, option to send messages and start chats, use Copilot, view profile cards and availability.
- File app: Find cloud and local files, preview file content, share with colleagues, filter using new filters, e.g., by activity, and use Copilot.
- Calendar app: view agendas or days, open meeting details, find events, edit meetings, use Copilot.
These apps will appear in the Start menu by default. What they have in common is that they introduce even more Copilot AI functionality on the Windows system. The integration focuses on app-specific tasks, for instance to find out what a specific user is working on at the time or drafting a new message to catch up.
Microsoft gives system administrators options to disable the rollout. Means, the apps won’t get installed automatically on managed devices, if the administrator does not allow it.
Home users, on the other hand, are once again kept in the dark by Microsoft. Users may uninstall the apps after they have been installed, according to Microsoft.
While there is a chance that Microsoft is making last-minute changes to its plans, for instance by making the apps install manually only, nothing of the kind has been confirmed officially at this point.
Now You: what is your stance on auto-installing apps on your devices? Feel free to leave a comment down below.
