I was on 8.1 using it quiet happily, windows 10 kept on asking me to upgrade and i kept on saying NO, the other day i went out, came back in and windows 10 was automatically upgrading on my laptop and i just had to leave it to do its thing, i did not want window 10 after reading all the horror stories, surprisingly though it all works so far, i read horror stories of the email not working, it does though, it seems actually nicer than the email on 8.1, i am still finding out bits on it like Microsoft Edge, so far though i like windows 10
