Bradley was fed up with the tedious memory tests following the restart so he decided to create a. Bradley is credited for implementing the 'Control-Alt-Delete' (Ctrl-Alt-Del) key combination that was used to reboot the computer. Back in the days, programmers had to manually restart the entire system whenever the computer encountered a coding glitch. Bradley (born 4 January 1949) is one of the twelve engineers who worked on the original IBM PC, developing the computers ROM BIOS code.

If accidentally pressed, as could happen in the case of a mixed OS environment, this can create the risk of short-term loss of availability of systems due to unintentional reboot. A locally logged-on user, who presses Ctrl-Alt-Delete when at the console, can reboot the system.
