Windows

I wish there was a modern supported version similar to XP. 7 wasn't bad but it was the first version where they started introducing features designed for touchscreens and trying to use the same OS for desktops and tablets. They should have designed separate software for "full feature" computers (desktops and laptops) and mobile devices. I don't think any of the subsequent releases have improved on 7 as far as the user experience. I'm a little surprised they haven't released a subscription based OS yet.
