The biggest one for me in simply the UI complaints. Agree almost 100%. It is ugly. Period. And no way of changing that. Something that past Windows Versions let me do. People are so quick to mention XP and its default theme. But that's just it. It was a theme and you were a few clicks away from setting the classic theme which made XP look and feel indistinguishable from the previous version. With all the added benefits that XP brought under the hood.

I'd love to get DX12. I'd love to get the better multiple monitor handling. But if an OS looks ugly as sin to me and there is no way to change that means that I will give that one a miss. Especially if all the other technical shortcoming mentioned here are in it as well. Certainly don't care about the constand reset of all default app settings after each upgrade.

To me Windows is not just a work horse to get things done and I don't care how ugly it is or how horrible it is to use it. There is a certain sense of style involved for me. Just like when I buy cars. Some people simply look for the price and gas mileage. Don't care about the color or what model it is. That's not me, I want a good looking car and I want to have a good experience driving it. Price and mileage matter of course as well but the design is still most important.

I still have 4 more years of life left in Win7 and I will in no way shorten that grace period by sacrificing a usable OS that also looks great for Win10. I also hope that history repeats itself again and MS will have no alternative but to prolong the Win7 support. Just like they did with XP back in the day. If not, I will see in 2020 where we are with vulkan vs dx12 and I will consider a full time switch away from Windows.
