Why Does Outlook automatically log me in without my email address and password?

Thanks Charles!  I thought maybe there was a setting I overlooked.  However, what you said mirrors my sentiments.  As does p brooks reply as well.

I have been having the same problem since/about 11/17/13  with 2 other emails address . I do not use msn .I have even restored my computer 2 times and it works good for 2 or 3 days .I assume it may have something to do with some updates from maybe Microsoft or internet explorer .When I looked into the programs installed on the day it starts to mess up Microsoft has installed a large number of updates .In the past when  Microsoft had similar problems they did not seem to be aware of it  .

I do not know were it came from  but I would also like this issue to be corrected  .Thank you for posting this problem .

So you're saying to create separate logon accounts for everyone, including a Guest account?  That's a pain...and it still doesn't solve the problem when I logon with my own credentials.  Not to mention, how many users are not technically literate to even create those accounts?  Microsoft must have code automatically passing MSN account data to any and all MSN "services." They can fix that.  And what makes them think their consumers want that anyway?   It doesn't matter whether I provide a Win8 logon password, Outlook still doesn't always require a password.  I did change the setting to allow me to logon without having to provide a password; that works well.  But still, when my MSN homepage appears, I click Outlook, and sure enough, I'm not prompted for a password.  And yes, when I logoff Outlook and return to the MSN homepage, I do click "sign out."  I sign off/shut down my laptop every night, and when I return the next time, yep, all I have to do is click Outlook, and it opens my e-mail account.  Like someone else said, anyone who uses my laptop would have access to my Outlook account. 

Microsoft should have left Win8/8.1 strictly for mobile devices.  Using a laptop, my sidebars constantly appear without my cursor even being in the vicinity, the screen constantly shrinks or expands, and my cursor bounces all over the place by itself.  But the auto logon to Outlook...that's annoying.  And like others said, where's the security in that?!  Sounds like all of us with Win8/8.1 should nix our Hotmail/Outlook accounts and use another mail service.

I need to know what i can do to make it be like windows 7,click on  and type my username and password.Not everyone that has windows 8 has this problem and they don;t have to create anything else,what can i do to make it work,do i have to uncheck or delete something?

Create a separate Windows user account for others to use or let them use the Guest account.
