IMHO the worst MS additions are the ribbon and metro interfaces. If people are that stupid that they cannot work out how to use a PC they should buy a mac instead!
Experienced users want to use keyboard shortcuts instead of silly icons.
Take for example finding a program (that is not a tile) to launch using Windows 8 you need to [Windows]+[Q] then start typing the name and hit enter yet in Windows 7 you can simply press the [start] button and type what you want in the search box. So much for making life easier.
Office 2003 is much easier to use as experienced typists could simply use [Alt]+[F]+[A] for example without the use of a mouse or touching the screen.
MS has a tendency to dictate what users want - pity that failed in Windows 8 with their start menu backflip. If MS wants to retain their reduced market share they need to start listening and giving users what they want because their Windows 3.x/95 heyday has long gone.
