ABC Security Protector
This free little application prevents other users from accessing low-level operations on your computer.
The way ABC Security Protector works is very simple. It has three options, all of which are protected by a password to protect against unauthorized access.
You can restrict the use of the MS-DOS console and applications that work in MS-DOS mode. You can also disable certain functions and restart keys F5, F6, and F8.
Users can only install Administrator rights.
The software is free, but after 30 days it shows a voluntary registration screen.
Keyboard coordinates can be found in the 'Readme.txt' file to work with the program.
