Long time windows hater here , use Macs and Linux, but I accidentally ended up with a windows PC a month ago. My first impression of it, with windows 8 installed, was oh my god, I heard that windows 8 was ten steps back, but I had no idea everyone was right. It was far less intuitive and usable than XP for example. But I decided to upgrade to windows 10 because I had read some good reviews but diehard mac users. From an out of the box factory recovery of windows 8 to an installed windows 10 was an 8 hour ordeal with a few cryptic steps one had to google along the way. It's truly mind boggling that that Microsoft can't figure out how it install a new OS in less than 8 hours. I was going as fast as one could go, the problem was not the dowload speed, that was instant comparitaively on my fast connection. It was that it had to do about 250 incremental and 2 major system updates before it would let you even request windows 10.
Anyhow once I got windows 10 installed. I was expecting to hate it. I'm sort of upset that it's so good. It basically is very close to a well configured linux mint in look and feel. The start menus is back and those crazy pants tiles with tonnes of crap you never asked for are wrangled into a small corner of the start menu and trimmed down to just the things you use a lot. The best description of the OS is that it no longer gets in your way so it's more like every other OS now.
It's still baffling in the directory layout and the mysteries of the registry. And since I have no idea how to use power shell I feel completely helpless; unistalls are inscrutable. And there's still the problem of crapware that burdens this. After you install Norton Utilities tries to trick you into installing it before revealing that it is payware. Within 2 weeks I got the entrire system trojaned with mal ware. I wasn't trying to do anything bad at all. I was trying to install an editor for minecraft mods and it came wrapped in something called openDownloader which just hosed my system. I told the windows 10 to revert it self, so I lost all my installs but at least got my computer back from the grave. What's meaningful about that ordeal is that it was the first time in my entire life that I got hit with malware. Iv'e certainly managed to download accidental malware on linux and mac, but it's always been possible for me to either inspect it enough to figure it out beofre the install or to install it under conditions (like not root or with a sandbox) that it was neutered or at the very least find every file that got touched. So malware has never been a problem for me before ever before I used a modern windows machine.
So between the 8 hour ordrdeal and the instant rooting I'm not a fan on Microsoft design. But if you are a savy windows user, have an already updated computer (not a factor reinstall) then installation will be a snap, and you will love this operating system. It's so mac and linux mint like.
