Pressing Alt + F4 while the mouse is over the small “Minimize” box is effectively closing the active window (or app) that owns that stuck UI element. This works because:
- Alt + F4 is a standard Windows shortcut to close the active item or exit the active app.
- When the “Minimize” box is visually stuck on screen, it is usually part of a window or process that is misbehaving. Closing that window/process with Alt + F4 clears the overlay without needing to restart the PC or Windows Explorer.
If the issue recurs and Alt + F4 does not help, additional options from similar UI problems include:
- Use Task Manager to end the problematic process:
- Press Ctrl + Shift + Escape to open Task Manager.
- Find the app or process that owns the stuck UI and select End task.
- Restart Windows Explorer (if the stuck element appears to be part of the shell):
- In Task Manager, locate Windows Explorer in the Processes tab.
- Right-click it and select Restart.
- As a last resort, sign out and back in, or shut down the PC instead of just restarting, which can clear some persistent UI states.
Alt + F4 remains the quickest fix when the stuck “Minimize” box belongs to the currently focused window.
