My main problem with every single version was "Where the hell are they hiding it this time?
That's been mostly my problem with Win8, I installed Classic Shell which brings back a lot of the look of older windows versions but there are still problems. New computers running Win8 were setting the office network to "public", which affects file and printer sharing. In older windows it was no problem to change a networks security level from public to private/work but in Win8 you have to go into User Account Controls, turn the security level there down and then you can change the network settings. Pain in the ass.
