Oh well, I like 8.1. But I’ll upgrade to 10 unless there is some type of major problem with it.
If you like 8.1, I predict you're gonna LOVE Win10. It's got all the best features of 8.1, and in my opinion they are more subtly and better done.
I didn't personally like 8.0 or 8.1, but I'm an old fart who still likes how Win2000 looked and felt.
