There seems to be a lot of embedded advertising in the OS. Also there is a learning curve to getting around. I miss my XP.
Oh and although it does boot faster, it is NOT that much faster to warrant a new OS imo.
I also dont like the fact that you now have to pretty much rent "Office" So I just reinstalled WORD 2007 and that works fine with windows 10. I guess with all new things it will take some getting use to.
