Why may not hide the taskbar
The Windows 10 taskbar hide settings are in the parameters - personalization - taskbar. It is enough to enable "automatically hide the taskbar in the desktop mode" or "automatically hide the taskbar in the tablet mode" (if you use it) to automatically hide.
If it does not work properly, the most frequent causes of such behavior can be
- Programs and applications that require your attention (highlighted in the taskbar).
- There are any notifications from programs in the field of notifications.
- Sometimes - Bag Explorer.exe.
All this is quite easily corrected in most cases, the main thing is to find out what exactly hides the taskbar.
Fixing the problem
The following actions should help if the taskbar does not disappear, even if the automatic hide is turned on for it:
- The simplest (sometimes can work) - press the Windows key (the one with the emblem) once - the Start menu opens, and then it will open it, it will not be excluded that with the taskbar.
- If there are labels on the task panels, open this application to find out that "it wants from you", and then (perhaps it will be necessary to perform any action in the application itself). Roll over or hide it.
- Open all the icons in the notification area (clicking on the button portering the up arrow) and see if there are any notifications and messages from running programs in the notification area - they can be displayed as a red circle, any meter, etc. n., depends on the specific program.
- Try to disable the "receive notifications from applications and other senders" item to the parameters - the system - notifications and actions.
- Restart the conductor. To do this, open the task manager (you can use the menu that opens on the right click on the "Start" button), in the Process list, find the "Explorer" and click "Restart".
If the specified actions did not help, try on one to close (completely) all programs, especially those whose icons are present in the notification area (usually can be done on the right click on such a icon) - this will help to identify which of the programs prevents hiding the taskbar.
Also, if you have Windows 10 Pro or Enterprise, try to open the Local Group Policy Editor (Win + R, enter the gpedit.msc) and then check if any policies are installed in the "User Configuration" section - "Start and Taskbar "(By default, all policies must be in the" not specified "state).
And finally, another way, if nothing previously helped, and reinstall the system there is no desire and possibilities: Try the Hide Taskbar side application, which hides the taskbar to the Ctrl + Esc key and is available for download here: thewindowsclub.com/hide Taskbar-Windows-7-HotKey (the program was created for 7, but I checked on Windows 10 1809, it works fine).
