a) "Everyone installs K-lite" Wow yeah. Everyone who torrents. All the other poor fellas have no idea. And I personally know those other poor fellas and they could not tell you want a codec is if you put a gun to their heads. Hell, my wife is one.
b) I WISH there was a Windows 8 live CD. MS does not want you to "try windows" they want you committed.
c) Drivers. Ok I give you this one. For the most part windows 7 is ok. Gone are the windows XP days where if you didn't have a disk on you, you didn't have your network card drivers.
d) There is NO PACKAGE MANAGER! None, ZERO. Windows Installer as a package manager is like saying my Garage is a parking lot + valet. Windows installer (this atrocity that is...) is used to... INSTALL software. It's a glorified unzip. There is no way to say "oh hey windows installer, I'd really like to install ruby 1.9.3 with sources" and it would say "give me an hour". Instead you say "windows installer? hello? ok to google!"... "to google" can often lead an unexperience used like my grandfather to download spyware.
e) Well. At least windows can be downloaded now as a free unactivated copy. Gone are the days where I purchase a copy of windows only to find out I can't get a legal disk image of windows 7 stand-alone. Only some upgrade, which is not upgradable from windows xp 32 bit.
