The Man Who Invented Ctrl-Alt-Del Keyboard Shortcut

Control-Alt-Delete is a very popular keyboard shortcut for rebooting a Windows PC, NT logon or for invoking the Windows Task Manager in XP systems.

The time saving Ctrl+Alt+Del keyboard combination was designed by David Bradley, a designer of the original IBM PC.

Bradley originally designed Control-Alt-Escape to trigger a soft reboot, but he found it was too easy to bump the left side of the keyboard and reboot the computer accidentally.

He switched the key combination to Control-Alt-Delete, a combination impossible to press with just one hand.

Bradley did not intend Control-Alt-Delete to be used by end users - it was meant to be used by people writing programs or documentation, so that they could reboot their computers without powering them down. But the key combination went on to become a cultural icon especially for hiding the Windows 95 BSOD.

With most modern keyboards, it's no longer impossible to press Control-Alt-Delete with one hand. I do it all the time.

Amit, thanks for the reminder about David Bradley and the Ctrl-Alt-Del keyboard combination, as it brought back a smile.

Just saw a quotation by him a few days back, and I'll leave it with you:

"I may have invented control-alt-delete, but Bill Gates made it really famous."
~ David Bradley, at a gathering on the 20th anniversary of the PC.

Funny, I was thinking of staring a tech blog yesterday and calling it Ctrl-Alt-Del, and on some search realized that there is CAD comics which has already taken that name ...
And then I was thinking about why we still have to use 3 buttons to do that task in this time and age? If we can manage to have a 'windows' button ... actually 2, why not have a single button to take over the CAD function or something else ... is it because it is a well established convention now? BTW, no disrespect to Mr. Bradley!

I second that. we can easily cover the ctrl-alt-del combination with our right hand. especially for people with big hands they can just accidentally press the key combo.

The story behind great work is like this. Like initially internet was not meant for common people (It was actually for US defense- ARPAnet).

judging by the video, bill doesnt have much of a sense of humor.
