An application or feature powered by Windows Copilot to assist users with tasks and productivity
The Copilot app window is running without the standard caption bar (minimize, maximize, close) and menu, similar to how other Windows apps can hide these controls in full‑screen or special modes.
For Microsoft apps that lose their menu bar or window buttons because of a full‑screen or special display mode, the fix is to exit that mode from within the app, or reset the app’s display settings. For example:
- In Office apps, if the menu bar or window buttons disappear in full‑screen mode, exiting full‑screen restores them.
- In Task Manager, a special “Tiny Footprint” mode hides the menu and tabs; double‑clicking the window border returns it to normal.
If the Copilot app has no visible control to exit its current view, close it from the taskbar (right‑click the Copilot icon > Close window) and reopen it. If the issue persists across sessions, update Windows and Copilot, or reset Copilot from Windows’ app settings.
If the problem continues after these steps, contact Microsoft Support so they can collect diagnostics and check for a display bug similar to other caption‑bar issues described in the references.
