Hi ,
Well apparently this is a bug, many users are having the problem, you can fix it using third party software, currently there is no confirmation that the taskbar will remain in the background.
Note: This is a non-Microsoft website. The page appears to be providing accurate, safe information. Watch out for ads on the site that may advertise products frequently classified as a PUP (Potentially Unwanted Products). Thoroughly research any product advertised on the site before you decide to download and install it.
