If your computer's system tray or icons are missing, it's possible that the taskbar isn't operating properly. To fix this, use Windows PowerShell to restore the taskbar. Right-click the Start button and choose Windows PowerShell (Admin). Check to see whether your system tray and icons have returned to the notification area. If they have, click OK.
If the taskbar's icons are gone and the system tray is empty, you must first repair the taskbar. If your taskbar is functional and just the battery icon is missing, you may resolve the problem by adjusting the taskbar settings. Open the Start menu and click Settings at the bottom of the screen.
How to Restore Missing or Disappearing Taskbar Icons in Windows 10
Windows XP does not include desktop icons or a taskbar. Users may find that their taskbar and desktop icons have vanished from time to time. There are several techniques for restoring the desktop icons and taskbar to the computer screen. One method is to use the Windows XP Repair Tool which can be downloaded from Microsoft's website.
The notification area, also known as the system tray, is found on the right side of the Windows taskbar. It shows icons for some of the apps that are now running on your computer, as well as any notifications. You can click an icon to see what's going on with that program.
You can add apps to the notification area by clicking their icons on the taskbar or searching for them in the Microsoft Store. Once an app is added to the notification area, it will continue to display there even after you close it. To remove an app from the notification area, just click its icon again.
Some programs may put a shortcut to their main page in the notification area. For example, if you often visit Facebook from Google Chrome, then clicking the Facebook icon in the notification area will take you straight to Facebook.
Finally, some apps may create shortcuts to settings pages. These are usually hidden menus that only make sense to that specific app; for example, the Netflix app might have a shortcut to quickly change the quality of your video stream.
These are just some examples of things that can go into the notification area. There are many other types of alerts that can be displayed there: new emails, chat messages, etc. The notification area is useful because it gives you quick access to information without having to open any apps full-screen.
How to Add System Tray Icons to the Windows 10 Notification Area:
The notification area (sometimes known as the "system tray") is positioned in the bottom right corner of the Windows Taskbar. It includes small icons for quick access to system features including antivirus settings, printers, modems, sound volume, battery status, and more. When you open the Start menu, it too is displayed in the notification area.
By default, the system tray contains a Power button, an audio control panel, and a network connection icon. You can add or remove items from the system tray by clicking the empty space next to each item.
For example, to delete a single item from the system tray, simply click the empty space next to it. To delete all items at once, click the empty space next to the first item, then drag your mouse down to the last item clicked.
If you want to move items around within the system tray, just click and hold on one item, then click another location within the notification area.
You can also customize the size of the system tray. By default, it takes up about half of the space on the bottom corner of the screen. However, you can make it smaller by clicking and dragging any edge of the tray, or larger by dragging it away from the corner of the screen.
To restore the original size of the system tray, click the start button, then click Settings.
