I don't mind the UX improvements for regular people. Just appreciate the ability to undo some of the changes when they are not helpful to my productivity. The context menu hiding and the start menu custom grouping loss were a pia when they disappeared. Thankfully both are back, by design or with tweaks.
I personally loved the old start menu. I always had mine go full screen when clicked on and ditched all the MS default stuff and made my own groups. I have now grown accustomed to the new Start menu and it works pretty well albeit once the custom folders returned (phew!).
I know that most "regular" users I encountered never really leveraged the full start menu properly from what I could tell. Not to say they should get rid of it, but just that most users probably don't feel the pain we do as they don't really appreciate how to use the tools. I know it was like a good few hours (days?) to re-customize a PC when installing a fresh OS for me, and most people it is just configure email, login with Google and/or Outlook.
And I'm really trying to adapt wherever possible as it becomes really painful down the road if you successfully fight it for too long, once the gig is up :-).
