And see no push for cloud storage. But I don't use the email login either.
I'd start with a local login like I do. Windows XP collected data too. I'm unsure if you meant something else but there are now many articles out but one thing that reverberates is that if MSFT was overstepping data collection there would be more articles about it.
I have avoided using cloud storage on both my Win7 desktop and my iPads. No real reason, I am just not comfortable with Cloud storage. I have also hesitated to upgrade to Win10 as I have the Idea that Cloud storage is pushed at you even more strongly. also, I gather even more personal data is tracked by Win10, which I also dont like. Is there a site with instructions for keeping Win10 from collecting data?
