Pro Key Lock is a powerful and easy to use utility that can be used to lock specific keys, key combinations and mouse functions.

Pro Key Lock prevents users from accidentally, or intentionally, pressing unwanted keyboard and mouse buttons. This makes it ideal to be used with kiosks, presentation computers, internet corners, seminar rooms, etc. Pro key Lock can also be used with specific-purpose computers (e.g. computers that ship with specific hardware or software) to prevent users from interfering with the operating system, with background services, etc.

Pro Key Lock works on Windows 2000, Windows XP, Windows Vista, Windows 7 and Windows 8.
