Right-click on the icon and this will bring up a context menu.
In the menu that pops up, select "Close Window" (the exact name of this option may vary depending on the program, such as "Exit", "Close All Windows", etc.).
If you have more than one window open, you can start by clicking the "Task View" button on the taskbar (which looks like a bunch of overlapping rectangles next to the search box) or presswindows
tab
Key.
In Task View, hover over the window you want to close, and a small close button (X) will appear, which you can click to close the window.
Hover your mouse pointer over the program icon on the taskbar without clicking.
Wait for the thumbnail preview to appear, then move your mouse over the preview of the specific window you want to close.
A close button (x) will appear in the upper right corner of the preview, which can be clicked to close the window.
If a program has multiple windows open and you want to close them all at once, you can:
Press and holdshift
at the same time, right-click the program icon on the taskbar.
