If Chrome is your daily driver and reinstalling it doesn’t fix the Windows 10 taskbar not hiding in full-screen issue, it is safe to assume that the problem is with Chrome. If it doesn’t, try Reinstalling the application in which you’re facing the issue. If you’re facing the issue in a browser, try opening other apps to see if the issue persists in them. If you’re facing the Windows 10 taskbar not hiding in fullscreen issue, chances are, it might be an issue with the app in which you’re trying to use the fullscreen mode.
Use A Different Browser Or Reinstall The App Pressing the F11 key to get out of the full screen and pressing it again to get into full-screen mode can also sometimes do the trick.
