The notification area, or system tray, is located on the right side of the Windows taskbar. It displays icons of programs currently active on your PC and any notifications.
To show or hide system icon, typically, in Windows 111/10, you have to open Settings > Personalization > Taskbar and click on Turn system icons on or off link. In the panel which opens up, you can toggle the switch to show or hide the system icons.
In Windows 7/8, to remove an icon from the notification area, you open Taskbar and Start Menu Properties > Appearance and Personalization > Taskbar and Start Menu. Under the Taskbar tab, click on Customize. Here you can choose to hide the notification area icons that you do not wish to see.
But this only hides but does not remove the icons. Many times, even when you uninstall a program, the icon for that program remains, although it may or may not get displayed. Windows may not remove the program icon of the uninstalled program icon from Notification Area Icons Control Panel applet.
