I have Windows 8.1 on my new-ish laptop. I gave in to the siren song of Windows 10 (FREE UPGRADE! SCHEDULE NOW!) and regretted it. I looked good at first overall but when I tried to type anything, it would pause every 3-4 characters and it took me forever to type simple things. I have no idea what the problem was - I tried to troubleshoot it but I gave up and went back to 8.1.
