I think you're confused. Windows 7 is terrific. Its predecessor, Vista, was horrible and a disaster for Microsoft, and Windows 8 is rapidly becoming as big a disaster.
But Win 7 rocks solid.
My dislike has nothing to do with its inherent functionality - it's the "new" set-up that irks me.
I miss the standard dropdowns and don't like the way the open windows look and act - I want everything the way it was - I'm too old to keep learning a new set-up every few years - 7 is not XP.
