When I switch from multiple monitors to a single monitor, the taskbar loses all the windows

When I have my laptop docked, I am connected to two additional monitors which I use alongside my laptop screen. My taskbars are set up to display only the windows on the monitor of the taskbar where the window is open. When I disconnect from the dock e.g. to go to a meeting, all the windows move to the laptop screen, but the taskbar there becomes empty; it doesn't even contain the windows that were on the laptop screen. I then have to go to Taskbar Settings and toggle Automatically hide the taskbar on and off to get them back. Is there a way to fix this?

    A supported workaround is to force Windows to render only on the laptop display after undocking:

    1. Press Windows key + P.
    2. Select PC screen only.

    This can help when the taskbar is still behaving as if another display is active after switching from multiple monitors.

    Also verify the taskbar behavior settings:

    1. Right-click the taskbar and select Taskbar settings.
    2. Expand Taskbar behaviors.
    3. Confirm Automatically hide the taskbar is unchecked.
    4. If the device is a 2-in-1, turn off Optimize taskbar for touch interactions when this device is used as a tablet. This setting has been identified as a cause of the taskbar hiding unexpectedly.

    If the taskbar still appears empty after disconnecting, toggling Automatically hide the taskbar off and on is a valid workaround based on the described behavior, but the context does not provide a permanent fix beyond the display-mode and taskbar-behavior checks above.

    Hi

    This looks like a Windows Explorer/taskbar refresh issue when the display configuration changes, rather than the windows themselves being lost.

    When it happens, press Ctrl + Shift + Esc, find Windows Explorer in Task Manager, right-click it and select Restart. This should refresh the taskbar without having to toggle auto-hide.

    As a workaround, you can also go to Settings > Personalization > Taskbar > Taskbar behaviors and temporarily change When using multiple displays, show my taskbar apps on to All taskbars, then test disconnecting the dock again.

    Microsoft's taskbar settings reference: https://support.microsoft.com/en-us/windows/customize-the-taskbar-in-windows-0657a50f-0cc7-dbfd-ae6b-05020b195b07

    If the issue continues even with Windows fully updated, I would recommend reporting it through Feedback Hub, as the taskbar is not refreshing correctly after the monitors are disconnected.
