Solve the problem of missing icons in the system tray area

Sometimes when a program has an illegal operation, the input method icon, time control icon, and volume control icon in the system tray area are gone. You can't judge what the current input method is, or even adjust the volume. What should I do? We can use the following methods to “retrieve” these icons: 1. Input method icon: Open the “Input Method Properties” window from the “Control Panel” under the “Input Method” tab. Select “Start the indicator on the taskbar” 2. Volume control icon: Open the “Sound and Audio Device Properties” window from the “Control Panel” and then check the “Put the volume icon into the taskbar” checkbox. 3. The taskbar is missing: Open the registry editor, find the StuckRects subkey under HKEY_CURRENT_USER\\Software\\Microsoft\\Windows\\CurrentVersion\\Explorer, delete it and restart the computer.
