I've got a old windows pc that is on the insider program. It only has 2GB and a dual core processor (E2160) it was getting sluggish with XP even after much optimising but with Windows 10 it's fast. Windows 10 is obviously a much leaner faster os and its got a great gui. Games run better and its much more logical and organised than windows 8. It also seems much better optimised than windows 7 plus it has a load of great new features. I've hated Windows operating systems for a long time, often bloated and slow but this seems to me a massive improvement. I shall definitely be upgrading my laptop and main PC with windows 10 in fact I'll be more than glad to see the back of windows 7 and 8. I think Microsoft are worried about competition like Steam OS because they have really put some effort in with this one.
