In the Windows 10 taskbar, the Task View button is displayed by default.
If you wish, you can hide it. Let’s see how to do this.
Turn off the Show Task View button. This one can be found between the “Show touch keyboard button” and “Search.”
Note: To show it, simply turn it on.
Launch Registry Editor.
I recommend backing up the Registry before continuing.
HKEY_CURRENT_USER > Software > Microsoft > Windows > CurrentVersion > Explorer > Advanced.
Double-click on the ShowTaskViewButton in the right pane.
Enter 0 in the Value data field. Hit the OK button.
To show, follow the above steps but replace 0 with 1.
