For some reason companies hate text now. Instead of a menu, you get icons with as minimalistic a design and as little difference between them as possible. Entering your user name and password is two separate pages for some reason now. Window borders have disappeared so instead of knowing at a glance where you can click and drag you have to closely watch your mouse pointer change. A big "Hewwo 2 U!" screen is added between turning your computer on and being able to enter your password as if you foolishly left your desktop in your jeans pocket and Windows wants to make sure you're not pocket-PowerPointing.
It's like they're trying to alienate everyone not intimately familiar with the system and appeal to the lowest common denominator at the same time.
