8 Changes in Windows 8 That Will Drive You Nuts
The reality of Windows 8 is that Metro is very much a 1.0, somewhat unfinished product. It's excellent from a stability and performance standpoint, but not everything is quite baked in just yet. This lack of polish is most obvious when digging around for common settings.
Metro has a PC Settings area, where you'd reasonably expect to find most of these controls. The problem is that a vast majority of them simply aren't there. To change settings like the screen resolution and firewall for example (two things that matter to both Metro and desktop), you have to jump to the desktop and go to the Control Panel.
