Never heard of this suggestion, but I have a feeling that yours might be correct. I have to test it out once I get back from my vacation.

AO3 and Stoic Joker, No offense, but your suggestions are incorrect since Microsoft Passport is not tied to IE, therefore clearing out saved usernames/passwords from IE will not clear out those from Microsoft Passport. cyberguest, I strongly advise you to follow my method as this is the only correct way to do this. Method #1: You will need to modify/create a key within the system. Open the Registry Editor, and navigate to the key: HKEY_LOCAL_MACHINE\ SYSTEM\ CurrentControlSet\ Control\ Lsa Create a Value called "disabledomaincreds" and set it to "1". Reboot will finalise the process. Note: This is generally only useful if you are setting up a system to be used by many users. Key Details: Machine Key: [HKEY_LOCAL_MACHINE\ SYSTEM\ CurrentControlSet\ Control\ Lsa] Value Name: disabledomaincreds Data Type: REG_DWORD (DWORD Value) Data Value: "1" = disable : "0" = enable Method #2 Here's a faster, safe, alternate way: must be logged in as ADMIN Go to Start + Control Panel + User Accounts + Choose your account + "Manage my network passwords" at the top left + Then delete whichever MSN accounts you don't need.
