With Copilot and Microsoft 365, you can summarize, ask questions, create an FAQ, and even compare certain files stored in OneDrive.

If you want to see recently opened files in Windows 11, then open Recent Items folder, use File Explorer Home, Taskbar, Start menu, etc.

If File Explorer keeps restarting on your Windows 11/10 PC, modify the BannerStore registry key, disable suspicious shell extensions, run antivirus, etc.
