Quite frankly, you have no idea what you are on about. I think you should stay away from Windows 10, or anything technical for that matter. If you are so scared of the cloud, maybe you should delete your email accounts and close your bank account... (I could make a massive list here of things you therefore shouldn't have). All of it connects to this scary cloud thing and sniffs your data one way or another... Where do you think your details are kept for this forum right now? In the cloud. Do you drive? Because guess what... All of the details required for you to drive, are stored in the cloud.
Aside the fact that you aren't forced to use OneDrive, what is stopping your computer being hacked? Your paranoia? Your virginity? Or you ugly face?
well you shouldnt be running windows at all in your case exspicaly not beta microsoft needs to collect data on your drivers you use and software you use exspicaly in beta software like windows 10 ms doesnt care that you downloaded x movie illegaly or that you chated with x people what they care about is that x movie doesnt crash media player or that the program you use to chat with x person worked right or that x driver for x device doesnt cause a bsod etc regardless the only way your keep all the info you want private is a non windows os or a windows pc not connected to the net
See, Gabe? That's your fault! Please, release the next build to us and we'll start talking about it and stop talking nonsense
