The Windows 8 UI is the most annoying thing I have ever dealt with -- and I am not alone in making that statement, even people I know who frequently use Windows have said so. Microsoft took a UI designed for touchscreens and tried to make it work on desktops and laptops; it is not even that great of a touchscreen UI.
I find it ironic that you talk about wasting time on config files. My experience in Windows is that doing anything beyond the 10 tasks Microsoft determined to be common results in hours of clicking through menus, configuration dialogs, and in some cases dealing with the registry editor. Trying to troubleshoot a problem is a nightmare. Trying to set up something unusual is beyond a nightmare.
