Here is an interesting problem, if you want to call it that, which Microsoft had to address when building Windows 8. We all want faster boot times and Windows 8 delivers on the front. The problem is that the boot times are so quick that when you need to enter the setup menu, by pressing F2/F8 during boot, there is literally no time to do it.
So, what did Microsoft do? Surely they are not going to artificially slow down the boot time to compensate for this, so they added a few new features to the
OS to make it easier to access these menus.
