Explorer is a bit of a mess. You can customise it - for example make it start in My PC (right-click Quick Access, then Options). But what I'd like to do is get rid of a lot of it. I've got used to it, and I don't remember Win7's explorer being any better, but I prefer XPs simpler version.

There are just two features in Win 10 that I'd really miss if I had to use Win7:

1. Virtual Desktops - I've used these in Linux since forever.
2. The File History backup system. This is really good - though if you don't want your backup drive permanently connected (to prevent ransomeware) then it's trickier to use.
