I have Windows 10 on my laptop which has MechWarrior Online and it runs fine, no issues. The only issue some people have with Windows 10 is that they don't like even the new Start Menu. If you feel the same, I have all my clients download Classic Shell and set it to make the Start Menu look like Windows 7. Also, Windows 10 sets Microsoft Edge as the default browser which I don't like, so I set Internet Explorer 11 as the default again and it works great.
