Microsoft is reintroducing the Microsoft 365 Copilot app, which will automatically install on eligible Windows PCs with Microsoft 365 desktop applications between mid-June and mid-July. Users in the European Economic Area will not be affected by this automatic installation. Admins can opt out of the automatic integration. The app will be activated by default, requiring no user intervention. Microsoft is not using the Windows Store for this installation; instead, it relies on the built-in Microsoft 365 Apps updater. Users can disable Copilot features on a case-by-case basis in specific Office apps or change privacy settings to block Copilot functionalities. Microsoft has also made Classic plans available in select regions for users who want a version without Copilot. Administrators can use Office policy settings to block connected experiences that drive Copilot functionalities but must opt out through the Microsoft 365 Apps admin center to prevent installation.
