Bill Gates has described the decision to use Ctrl+Alt+Del as the command needed to log on to a PC as a mistake.
Originally designed to trigger a reboot of a PC, it survives in the Windows 8 operating system as the command to access the task manager toolbar and is still used in older versions to log on.
In an interview, the Microsoft co-founder blamed IBM for the shortcut, saying he had favoured a single button.
IBM engineer David Bradley invented the keyboard shortcut.
Originally, he had favoured Ctrl+Alt+Esc, but he found it was too easy to bump the left side of the keyboard and reboot the computer accidentally so switched to Ctrl+Alt+Del because it was impossible to press with just one hand.
During IBM’s 20th anniversary celebrations, he said that while he might have invented it, Bill Gates made it famous.
His involvement in the invention has made him something of a programming hero though- with fans asking him to autograph keyboards at conferences.
The shortcut, also known as the three-finger salute – came to prominence in the early 1990s as a quick fix for the infamous “blue screen of death” on PCs.
Speaking at a fundraiser at the Harvard University, Gates said he thought that it had been a mistake.
“We could have had a single button, but the guy who did the IBM keyboard design did not want to give us our single button.”
While some loathe the clunky command, others took to news site Reddit to express their fondness for it.
“I feel a single button would be a mistake,” said one.
“There’s a conscious commitment and in many cases a sense of satisfying sword play in executing the two-handed finger strike of Ctrl-Alt-Del.”
