SecureIt Pro is a cool free lock-down program for the PC. The best thing is that it comes with an inbuilt password reminder function for incurably amnesiac muppets like me.
‘Using it is easy – just enter a password and click Lock – SecureIt Pro does the rest. Disabling the main Windows key functions, like Ctrl+Alt+Del, Alt+Tab, the Windows key, and the Ctrl+Esc key combination; SecureIt Pro can also disable the Windows boot keys; detect for cold boots; allow other people to leave messages; log incorrect password attempts; or even hide itself every few seconds.’
