The "Show Desktop" icon, usually in the computer taskbar, is a button that immediately minimizes all open programs when the computer is turned on and makes the desktop display. It can right-click in the blank space of the taskbar and select "Quick Start" in the toolbar to display this icon, or it can not display this icon without selecting "Quick Start".

You can click the triangle icon in the lower right corner of the computer to display more small windows with icons, and then click "Customize" to display customized windows. Here we can see all the programs running in the background, and the back of each program will also show whether it is displayed in the front end. Drag down again to find the program you want to display, click the drop-down arrow, and a drop-down menu will appear. Select "Show only notifications" as "Show icons and notifications", and then click "OK" in the lower right corner of the window to complete the setting.
