The kbfiltr.sys file is a system driver utility that is used by Microsoft Windows to allow the associated firmware or device driver software component to communicate with the system and the keyboard hotkeys or shortcut keys embedded in certain Acer laptops. This means the kbfiltr.sys file is distributed alongside other SYS driver files, certain EXE application resources, some DLL (Dynamic Link Library) modules, specific background process items and various components that are used by these associated firmware resources and driver software distributions. This means the kbfiltr.sys file is packaged into the installer distributions of these firmware components and device driver software resources, which also means the kbfiltr.sys file is placed in the system upon the installation of these firmware distributions and driver software packages into the Windows-based systems of supported Acer laptop models. The kbfiltr.sys file is specifically deployed as one of the components of the Dritek HotKey Keyboard Filter Driver module, which is an applet built into these associated firmware and driver software components of compatible Acer laptops.
