Remove saved credentials or password stored in Windows 7

If you are facing problems regarding connecting to a network drive and the system did not prompt you for a username and password. Most likely, you had already a password being saved in the system already. You could type this command to check the credentials that had been stored previously.

rundll32.exe keymgr.dll, KRShowKeyMgr

From here you can remove authenticated network shares so that the next time you will have to type in the credentials again.
