giant Microsoft said that it decided to kill off the start button in Windows 8 because punters were not using it.
According to PC Pro, it has been assumed that Microsoft removed the Start button to force people to familiarise themselves with the new Metro Start screen. Chaitanya Sareen, principal program manager at Microsoft said that there had been a trend after Windows 7 to avoid the start button. He said that when Microsoft evolved the taskbar it saw that people prefered pinning applications on the taskbar. As people pinned Start menu usage dramatically dropped.
Sareen also claims that people are taking advantage of keyboard shortcuts to open applications, instead of resorting to the Start menu. All they have to do is press the Windows key and 1 and you’re already in the first thing on your taskbar. Of course this is dependant on people knowing that.
