Question: When I sign onto Messenger in Windows XP, there's a drop-down menu of sign-addresses I can use. Is there a way to keep those addresses from appearing, so I have to type it in each time? Answer: Yes there is a way, although you will need to modify/create a key within the system registry. 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 usefull 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 Heres a faster, safe, alternate way: must be logged in as ADMIN Goto 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
