The taskbar won’t hide if a program or notification is keeping it active. To fix it, check for open apps or system notifications, enable “Automatically hide the taskbar” in Settings → Personalization → Taskbar, and restart Windows Explorer if needed.
The taskbar may not hide due to active apps, notifications, or glitches in Windows. Restart File Explorer, turn auto-hide off and on, and check for apps needing attention. Disable notifications or system tray icons causing it. Update Windows and run a quick restart. If it persists, check taskbar settings or perform a system troubleshoot.
