MSN Messenger
This is a pretty common problem with MSN Messenger users. Besides being annoying if it is unwanted, it can be dangerous if you access your MSN account from a public computer-that computer will also remember your login information. Because of this, it is important that your account not log you in automatically. It is easy to do, but you need to check a few things first.
I see that you’ve already checked that the “Allow Automatic sign in when connected to the Internet” option is disabled. You also need to go to Tools, then Options and then General tab when in MSN and make sure that the “Automatically run when I log into Windows” option is disabled.
Sign Out
If both of these are disabled, then the best way to get the computer to forget who you are is to simply sign out. Many MSN users just close the program without signing out, leaving all of their information live on the computer. When you are done using MSN, go to File and then Sign Out. This should erase the information and you should have to enter your password the next time you want to access Messenger.
Remove Passport.Net
Another way to disable an automatic login is to follow these steps:
- Go to Start and then Control Panel.
- Click on User Accounts.
- In the Advanced tab, click on Manage Passwords.
- Find “Store User Names and Passwords”.
- Choose Passport.Net/*. Click Remove.
- Click Close and then click Ok.
Following these directions should ensure that MSN will stop logging you in automatically. If you have used MSN Messenger on a public or a friend’s computer, log onto MSN and change your password. The other computers will have your old password on file and should no longer be able to access your account.
