First, go to control panel, scroll down untill you see
user accounts (should be near the bottom) Open it.
Click on the user acc. that this issue is in (ie Your
Account) After doing so, you should see Change my name,
Change my password, etc. At the top left hand corner of
that screen, you should see "Manage my network
passwords" --- click on this. Now I don't remember what
it is named, but whichever is not an e-mail address,
click on it and then click on remove. This will prevent
Messenger from Auto Signing in. I hope this Solves your
problems, and if you have any other questions, please
feel free to ask. Take Care and Have a Nice Day
