As soon as a user has to open a Windows management console, they've become a system admin, too. Device Manager? That's sysadmin. You seem to have missed my point about 'preconceived notion of what an operating system looks like'.
Half the stuff you're complaining about is equally stupid in windows. Have to download a tool from some slightly dodgy site to fix your problem? Two shots. Windows config file edited? A shot. Install a .reg file? have another shot. Run something in an cmd window that's been raised to Administrator (not easily discoverable)? have a shot. Have to kill something in Task Manager? Another shot. Ignore the log, "just reboot to clear the error"? Another shot. Random new icon on your desktop from your mystery tool? Another shot. A brand new phone-home tool-specific updater and possible spyware? Two shots. Windows auto-update does an autoreboot overnight and kills open documents? Have another shot. Never suggesting looking in the logs for an insight to the error? Another shot. If the installer is actually a preloader, and it loads an unknown-size payload? Have a shot. Download "mouse drivers" or "network drivers" from your motherboard provider and they're somehow bigger than 100MB? (even bigger than 1MB?) Have a shot. The tool you're looking for is described on a shitty page full of ads for crapware? A shot. The tool you're installing has a drive-by download of some shitty toolbar, with a pre-checked tickbox? Have another shot (hello Adobe Flash!). You need some special media library just to view support resources from your vendor? Take a shot (hello, Silverlight!).
What about the glorious nature of the AMD GPU Catalyst drivers? On a new Windows install using inbuilt drivers, the display is understandable low res, 640x480. You can open the Catalyst drivers to start setting them up, but you can't see the OK/Apply button, and you can't move the top of the window off the screen, because it's taller than 480 pixels. If you don't know how that screen should work, it's just not discoverable. It's been a problem for years.
You're picking and choosing pretty damn hard there, my friend. OSX has largely solved a lot of these problems (mostly by locking things down hard, particularly on the hardware side of things), but Windows sure hasn't.
