A free Keyboard Filter Driver for Windows Embedded Standard 7 from Elbacom
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 Embedded Standard 7 only and ships can be installed easily with a single setup file.
