Not using the latest version is often the best solution.
Win7, office 2007, Adobe CS2, autocad 2011 will do wonders on your I7. Honestly.
I'll squeeze Office 2010 here because only that version (earliest / unclear later) combined with a custom add-in, gave me unprecedented control over Excel I have never seen before or since, including a god mode and like 2.5 menus.
But prob is "Win 10" is becoming one of those milestones, where "MS is Doing Things" so I wanna stay current on that one.
My current plan is to give it 4-7 more months to shake out.
