By default, Microsoft Windows 7 displays several icons in the lower right corner of the PC desktop (also called the "System Tray"), including the Volume Control icon. However -- especially at first boot up of the Windows 7 operating system -- you may find that one or all icons are missing from the "System Tray." Use the Registry Editor utility in Windows 7 to quickly resolve issue and enable the Volume device icon to appear in the "System Tray."
1). Log in to the Windows 7 computer, using the credentials of an Administrator account on the computer. Click the "Start" button, then click "Search" and enter "regedit" in the "Search" box and press the "Enter" key.
2). Navigate to the "HKEY_CURRENT_USER\Software\Classes\Local Settings\Software\Microsoft\Windows\CurrentVersion\TrayNotify" directory in the "Registry Editor" window that appears. Click the "IconStreams" item once to highlight it and then click the "Edit" menu at the top of the "Registry Editor" window. Click "Delete" in the menu that appears and click "Yes" to confirm deletion.
3). Click the "PastIconsStream" item once to highlight the item and then click the ""Edit" menu at the top of the "Registry Editor" window, click "Delete" in the menu that appears and click "Yes" to confirm and delete the item. Click the red "X" at the top right of the "Registry Editor" window to close the window.
4). Right-click the Task Bar and click "Task Manager" in the menu that appears. Click the "Processes" tab in the "Task Manager" window that appears. Find the "explorer.exe" process in the list of processes and click on it once and then click the "End Process" button. Click "End Process" again to shut down the "explorer.exe" process. Click "File" in the "Task Manager" window and click "Run" in the menu that appears. Type "explorer" in the "Run" box and press the "Enter" key. Click the "File" menu in the "Task Manager" window and then click "Exit Task Manager."
5). Click the "Start" button on the PC desktop and click the "Search" box and type "Customize icons" in the "Search" box and tap the "Enter" key. Click the "Customize icons on the task bar" item that appears and click "Turn system icons on or off" and then set the "Volume" to "On." Click the "OK" button and then click "OK" to save the settings.
