Microsoft to remove the Calendar, People, and Files mini-apps from Windows 11

⚡ The gist in 5 seconds - Microsoft is ending support for the Calendar, People, and Files mini-apps — they will be removed after December 16, 2026. - The apps were automatically installed on Windows 11 machines with linked Microsoft 365 accounts starting in late 2025. - Data will be preserved, but no more security updates will be released for these mini-apps. ### 🔍 What was found Microsoft has announced that support for three mini-apps — Calendar, People, and Files — will end on December 16, 2026. These are the lightweight apps that began being automatically installed in late 2025 on computers running Windows 11 with linked Microsoft 365 accounts. The idea was quick access to important information, such as contacts; the company has not disclosed its reasons for dropping them. While the mini-apps themselves will disappear, the associated data will remain: contact information is already stored in the Microsoft 365 cloud, meaning the mini-apps were just one way to access it. Automatic installation has already stopped, but there is no automatic removal. On home PCs they can be uninstalled the usual way, while enterprise administrators will have to remove them manually and additionally configure Intune to stop deployment. ### 💡 Why it matters The decision looks unexpected given how actively Microsoft was rolling Copilot features into these mini-apps and even announced new capabilities marked "coming soon" — which, evidently, will now never arrive. Users who have grown accustomed to Calendar, People, and Files should migrate their workflows in advance: for calendar and contacts, Microsoft recommends Outlook and Teams; for file work, the Windows search field, File Explorer, SharePoint, and OneDrive. Quick access to information also remains available through the AI assistant Copilot. ### 🧩 Context The mini-apps appeared as a lightweight way to work with Microsoft 365 data, and in late 2025 the company began installing them automatically for Windows 11 users. Now comes the reversal: only a few weeks remain until support ends, and no security updates will be released for these apps. Those who actively used the mini-apps should move their data and switch to the Microsoft-recommended services to avoid losing convenient access to calendar, contacts, and files.
