Why uses hate the Windows 8.1 Interface

A lot of people hate the new interface but why, thats very simple. It may be well organized but still there are some haters.

• Hidden Functionalities
  A lot of Old and New function are hidden deep in the new interface, like the shut down menu, people don't want to spend a lot of time to shut down. and it's not the only thing that's hidden there are a lot more things.
• Big change
  some users can't handle the change of the new interface, they just are so well known with the old start menu and they can't handle the big change. if they had done it gradually users didn't have to learn it the hard way.

however i think it's still a major improvement
