This is not expected taskbar behavior in Windows 11. A practical first path is:
- Confirm auto-hide is the setting involved
Go to Start > Settings > Personalization > Taskbar > Taskbar behaviors.
Check whether Automatically hide the taskbar is enabled. - Toggle auto-hide off and back on
In the same Taskbar behaviors section, clear Automatically hide the taskbar, then enable it again.
This resets the behavior Windows uses to reveal the taskbar. - Check whether the problem happens only with certain apps or windows
Some windows, especially fullscreen-style or borderless windows, can affect whether the taskbar stays visible. If it only happens with specific apps, that points to the app window behavior rather than the taskbar setting itself. - If using more than one display, review multiple-display taskbar behavior
In Start > Settings > Personalization > Taskbar, expand the multiple display options and verify the taskbar settings there, since multi-monitor handling can affect taskbar behavior. - Restart Windows Explorer
Open Task Manager, find Windows Explorer, right-click it, and select Restart.
This refreshes the shell that controls the taskbar and can correct cases where the taskbar appears behind windows.
The screenshots and description match reports where the taskbar behaves as though it is behind open windows instead of appearing when the pointer reaches the bottom edge. The supported settings available in Windows 11 are mainly under Taskbar behaviors, especially Automatically hide the taskbar.
