Windows XP Home, Sp. 3
After years of successful operation, the volume control on the taskbar disappeared. If I go to Control Panel-Sounds and Audio Devices-Volume, the “place volume icon in the taskbar” box is checked. If I uncheck/ apply/ ok, then check/apply/ok a couple of times the icon will appear and operates correctly. However, when I reboot the icon is gone again. In “Taskbar and Start Menu Properties”, the “Hide inactive icons” box is not checked.
What has happened and how do I fix it?
