The Keyboard Filter Driver allows you to block any unwanted key combination or even single keys. This is done by a kernel mode filter driver which filters out the key presses before they are processed by the system.
Examples for unwanted key combinations on an embedded system are: Ctrl+Alt+Delete, Ctrl+Shift+Esc, Win+E, etc. All these key combinations can be filtered with this driver.
The driver is available for Windows 7 or Windows 8 based systems and ships can be installed easily with a single setup file.
The configuration is done via the command line tool kbfmgr.
/enable Enables the filter driver
/disable Disables the filter driver
/addset <+|->scancode[,<+|->scancode[,...]] Creates a new set of filtered scancodes
/modifyset <setid> <+|->scancode[,<+|->scancode[,...]] Modifies a new set of filtered scancodes
/deleteset <setid> Deletes a set
The scancodes for the keys must be entered in decimal format.
