Verify Sign-in Name Or E-mail Address to Validate Display Names
A contact's display name can be different than their sign-in name or e-mail address. Multiple contacts can have the same display name. To avoid information disclosure to unknown individuals, users should verify a contact's sign-in name or e-mail address before responding to messages. The user can view the sign-in name and e-mail address by right-clicking the contact and choosing Properties.
Default Registry Settings
You should be aware of the registry settings that impact security. If a value has security implications you will find a Security Note in the registry settings documentation.
For more information, see Windows Messenger Registry Settings.
Ports
The Windows Messenger application uses network ports to communicate with servers and directly with clients. For more information about these ports, see Windows Messenger OS Design Development.
