Windows 8 operating systems refresh the desktop screen automatically whenever it detects a change. This generally takes place when a new icon is added, when a file name is modified, or when you uninstall a program that had previously placed an icon on the desktop. However, in some cases, the system does not auto-refresh the screen due to unexpected system behavior, or a delay is caused by slow computer performance. In such cases, you can refresh the desktop manually to update the latest changes applied to your desktop.
Click or tap the "Desktop" tile from the default Start screen. This hides the contents displayed in favor of the Windows 8 desktop.
