Do I need HP extended capabilities 5.3, HP Image Zone 5.3, and HP Imaging Device Functions 5.3 altogether? They are taking up too much space.
The applications were provided during the installation of your system meaning that if your computer was bought from the HP Official Store or a 3rd party representative then these applications were installed by default and they are OK to uninstall. The products have no impact on your system's good functionality unless you use a printer/scanner - in this case you need the HP Imaging Device Functions utility.
