The Device Manager is another useful Windows Control Panel applet which allows users not just managing drivers and devices but also disabling specific pieces of hardware on a Windows computer. However, there are times when things could go wrong with the Device Manager as some users reported that their Device Manager is blank and shows nothing at all.
