(4) Keyboard Filter
The Keyboard Filter is a feature to block specific key input from the keyboard. In addition to
providing predefined lists of keys and key combinations (e.g. Ctrl + Alt + Del, W
L etc.), you can also define your own custom keys.
After logging in with an account with administrator privileges, configure the keyboard filter
using the Local Group Policy Editor (“gpedit.msc” command).
For details on keyboard filter, refer to “Keyboard Filter Technical Reference (Standard 7
SP1)” by Microsoft Corporation.
