Hello, I will be sharing my Windows 8 laptop with my brother. I would like to log into my laptop with my microsoft account while my bro will use a local account with his own user ID and password. I understand that signing in with a microsoft account will sync all my online details such as skype, skydrive, hotmail to my PCs. In this case, will my bro be able to access my emails and all personal stuff if he logs into my laptop using his own local account? Thanks.
