Well, didn't try them yet, will download them when I get home from work.
What I've heard is that W10 is best windows from MS, like XP v3.0
Well, it all depends on person and for how long did you use previous version of windows.
I was using xp for 8 years, then I got windows 7, I did need some time to adjust, but I never look back now.
I've also heard that windows 10 is based on the same architecture as windows 7, so everything that worked on W7 should work on W10 too.
The best thing you can do is to test it by yourself.Everyone can say "I like it", but if you don't like it you don't like it, right.
