I found the file WindowsLiveLogin.dll. I understand it's a legitimate Windows file but what does it do?

windowslivelogin.dll
    WindowsLiveLogin.dll is a part of Microsoft Windows Live.
    WindowsLiveLogin.dll is a Windows Live Sign-in Helper.
    Manufacturer: Microsoft Corp.

It authenticates you on a microsoft site with the Live ID

Ok i looked a little more about this "windows live sign-in assistant" .. Are the email addresses saved locally in the PC? Or can I use the list from wherever computer I login to hotmail ex. I log into my mailbox and the addresses appear in the log in screen. Would be handy

Locally.
