I'm not happy with this. I waited on XP until they got over vista, and I'm still on 7 while I watch in bemusement at the windows 8.1 nonsense. Now, with windows 10, my security updates will come bundled with my unwanted OS changes. I doubt microsoft will let people opt out of unwanted cloud-based security risks or crazy interface experiments.
Care to tell me what your issue is with Windows 8.1? I've been using 8/8.1 for well over a year now, and it has been, perhaps, one of the best installments of the Windows line of operating systems I have ever used. There are a variety of third party applications and workarounds that can effectively re-patch explorer.exe to completely disable Modern UI and bring back the old start menu (think Start Is Back).
I'll stop you here: Why would I use an operating system so user-hostile that it's own advocates are saying "it's ok, lots of programs are available to unfuck it!", when the previous installment is on every level technically sound and doesn't require the unfucking?
