I myself set up windows 8 to sign in with a local account instead of a shared one like that. You won't have those issues then.
Me, I created a hotmail account specifically for Win 8 and related Microsoft correspondence, I use it for nothing else, therefore there are no overlaps with my other accounts, etc. I'm a bit like kona in that I like to keep things in their proper place, rather than here, there and everywhere.
I will use Skydrive for items I have terrestial copies of and aren't too important/personal, but only so that I have access to them if needed when I'm out and about. Other than that, I want my stuff organised and compartmentalised in its designated location.
