Since I feel that email login is a security problem waiting to happen, I use a local login on W8 and W10.
today I could not login to my windows livemail, which has been working perfectly since windows 10 install January this year. Could not even login to security maintenance under control panel. I just happen to have other issues with windows on another computer logging into microsoft games. I decided to try logging in with my email account and password, and guest what it was fixed. This is Microsoft controlling our world. What really was the worst, Both my computers on completely different IP address and accounts came up with the same desktop background. The background was on the other computer and the pic was not even on the computer and no network between the two. No one should have to log into their computer with their email address. Come on Microsoft fix this
