Hi,
Nice to meet you! My name is Randy and I'm an independent advisor.
If the taskbar doesn’t reappear when auto-hide is enabled, You can try this, first try restarting Windows Explorer (press Ctrl+Shift+Esc, right-click Windows Explorer, and choose Restart). If that doesn’t help, check Taskbar settings to confirm “Automatically hide the taskbar” is enabled and applied to the right display. Finally, update your graphics driver through Device Manager, since outdated drivers can stop the taskbar from refreshing properly.
Kind regards,
