It's been steadily downhill since 7 though. Integration of spyware got it's foothold in 8 and now that we are at 11, you've got a completely spyware ridden OS, and then on top of that, basic things like context menus, audio drivers, screenshot tools, and connecting monitors to laptops is broken.
Many of these issues were ironically the same issues that stopped me from running Ubuntu Dapper Drake when I first installed it. It's just an unacceptably bad product from Microsoft, and if businesses weren't vendor locked (specifically the business I work for) I'd never even look at it, much like I don't look at Lotus or Corel products.
