The leaked screenshot, obtained by PCbeta, reveal that Microsoft has removed the button. This was probably done as part of Microsoft's Metro-style UI effort to make the user interface more intuitive across multiple devices. While the Start button may be gone, the button's core functionality will be retained using a 'hot corner'. The hot corner, which you activate by either touching or mousing over one of the screen's four corners, will supposedly activate a start-style menu screen when the operating system is both desktop and Metro UI mode. The Live Bar, which allows you to pin frequently used programs to, will continue being used in Windows 8, according to the report.
