The sidebar in Windows 10 is a vertical pane that appears on the left-hand side of the screen. It provides quick access to frequently used folders, such as Documents, Pictures, and Music, as well as settings and other tools.
There are several ways to close the sidebar in Windows 10. One way is to simply click on the small arrow located in the top-right corner of the sidebar. Another way is to right-click on the sidebar and select the “Close sidebar” option.
