Bill Gates admits Control-Alt-Delete 'was a mistake'

Microsoft co-founder Bill Gates has admitted that the Control-Alt-Delete key combination was "a mistake" that he hadn't wanted to be used.

"We could have had a single button but the guy who did the IMB keyboard design didn't want to give us our single button," Gates said in a talk at Harvard University. "It was a mistake."

The 57-year-old, now a philanthropist with the Bill and Melinda Gates Foundation, was talking about the early years of Microsoft and the Windows operating system.
