Identify program that prevent Taskbar's auto-hiding

Question

Hello,
Normally the taskbar of windows can be set as auto-hiding.
However, occasionally some program can prevent this auto-hiding
from working. Examples are that when a download is finished in IE it gives a notification bar at the bottom, and when the IE windows is not in the front, the icon will be darkened somehow in blue shade in the taskbar, which also prevent taskbar’s auto-hiding.
Until one handles that notification by clicking it, the taskbar will continue to be displayed.
When multiple programs are open, sometimes when this happen it is
difficult to know which prevents the auto-hiding to taskbar, particularly when the program does not display the icon as highlighted. In these situations is there other ways to prevent such? Can it be done programmatically like with
Powershell?

Hi,
I doubt there is no such PowerShell command to do this job. In addition, I made a test in our testing enviroment, there is no such problem as your description. After IE finished download files, its notification won't prevent TaskBar auto hid.
For your situation, please check if it is other app that was running prevent TaskBar auto hid.
