Windows 10: Taskbar Does Not Auto-Hide on Main Display Unless Start Menu is Opened and Closed

I am working on a Dell Precision 3560 on Windows version 20H2 OS Build 19042.2728. My computer is managed by my organization so I cannot easily modify things requiring administrator access. Issue Description: Mousing over the task bar on my Main Display causes it to pull up but it does not go back down. The taskbar will stay unhidden without shifting the windows to accommodate, causing the bottom portion of the active window to be blocked by the taskbar. This does not happen when mousing over the taskbar on secondary or tertiary displays. The issue also occurs if I disconnect my laptop from ex

:)

 

Taskbar hides and shows itself after opening start menu.

Steps:

1. Using HDMI for a second monitor.
2. Open start menu using the icon.
3. Close start menu using the icon.
4. Click anywhere other than the task bars. (e.g. an open window, the desktop, even the first monitor's desktop)
   
5. Taskbar on second monitor slides down to be hidden.
6. Taskbar then immediately slides up to reappear.

If after closing the start menu (step 3), you click on the taskbar, then click outside the taskbar, this behavior does not occur.

Performing the steps on the main monitor's taskbar does not produce this behavior.

This has been happening for as long as I can remember using this laptop (~3years), with different nVidia drivers and Windows 10 updates.

 

how to effectively hide or disable the taskbar?

Hi,



Did you try the “Auto-hide the taskbar” option from Taskbar properties?



If you have not tried it, I would suggest you to follow these steps and auto-hide the taskbar:

• Right click on Taskbar.
• Click on Properties
• Check the box Auto-hide the taskbar.
• Click on OK.

Hope this information helps.

 

Auto hide taskbar not unhiding

This was working fine and for some unknown reason it stopped. I have the taskbar on auto hide and when I move my mouse to unhide, it will not show the taskbar. I did not change any settings or download anything new so do not know what happened. I tried taking
auto hide off and it appears fine, then turned auto hide back on and still the taskbar will not unhide. Any suggestions how to get my taskbar to unhide without having to turn it on/off?

I also can not close one window, it makes me close all windows. The little + sign is gone to open a new window I have to go to the right side, open the drop down menu and click New Window. None of this was like this yesterday, the taskbar worked perfectly
so I am very confused. Please help me get my taskbar back to working normal again.
