Hello Nitish Maurya, thanks for sharing this in our community.
Sorry to hear that your taskbar isn't hiding properly, especially when you've enabled auto-hide and are trying to focus or enjoy a clean screen experience.
One quick fix that often works is restarting Windows Explorer. You can do this by pressing Ctrl + Shift + Esc to open Task Manager, then finding Windows Explorer in the list, right-clicking it, and choosing Restart. This refreshes the taskbar and can resolve auto-hide issues.
Another thing to check is whether any background applications are interfering. Some apps like media players or remote desktop tools may block the taskbar from hiding. Try closing background apps one by one using Task Manager and see if the taskbar hides properly afterward. If that doesn’t help, you might want to run the System File Checker to fix any corrupted system files. Open Command Prompt as an administrator and run the command sfc /scannow. Once the scan completes, restart your PC.
There are a few common causes for taskbar auto-hide issues. Background applications or notifications can prevent the taskbar from hiding. Sometimes, glitches in Windows Explorer interfere with taskbar behavior. Corrupted system files or outdated drivers, especially graphics drivers like NVIDIA, can also cause UI inconsistencies.
Hope this works for you.
Kind regards,
John Oli
