Re: Microsoft middle(nuisance)ware.
I use both every day, and I can't deny that Windows 7 is far easier to use than Windows 10.
I guess it depends what you're actually doing all day, but I tend to run the same software most days and the OS doesn't get in the way of me doing that. I've heard it opined that Windows 10 is a little faster and a little less resource heavy than Windows 7, but I have no solid evidence to back that up. I noticed virtually no difference in my day to day work when I switched to Windows 10. (I won't say the procedure was totally pain free, but it was a lot less painful than most macOS updates.)
If anything, Windows 10 is slightly nicer to use - being able to layout the applications I use the most (that aren't pinned to the task bar) the way I want in the start menu is way better than the constantly reorganising recent programs list of Windows 7, and the applications list is infinitely better than the All Programs menu from earlier incarnations of Windows.
The *one* issue I do constantly hit is that the Fn key is right next to the Windows key on my laptop and more often than not I hit the wrong one and suddenly enter Windows Tiling Mode instead of going to the start/end of the line. I should probably figure out how to disable the Windows shortcuts, but well... I'm lazy. :)
