Windows 7: Manage User Stored Credentials (User Names and Passwords)

When your computer tries to connect to other devices on your local network that requires a username and password.  Windows will attempt to use the currently logged on user credentials to authenticate that connection. If that username and password doesn't work, it will attempt to find one in the stored credentials. If these credentials are not available on the local system, you will be prompted with a username and password dialog box with a check box titled Remember My Password.

If you checked the Remember My Password check box, the information will be saved to the stored credentials area of your user profile. Then, when you connect to the same resource at a future date, Windows will be able to use these credentials to automatically authenticate your connection.

If you wish to view or change any of the user information in the stored credentials, you can do so by accessing the Stored User Names and Passwords tool.

• Open the Run dialog, press the WinKey+R.
• Type "rundll32.exe keymgr.dll, KRShowKeyMgr" and press the Enter button.  

Once the dialog is displayed you can change or delete any of the stored credential information.
