+When the previous box (\k{config-username}) is left blank, by default,
+PuTTY will prompt for a username at the time you make a connection.
+
+In some environments, such as large corporate networks with \i{single
+sign-on}, a more sensible default may be to use the name of the user
+logged in to the local operating system (if any). This control allows
+you to change the default behaviour.
+
+The current system username is displayed in the dialog as a
+convenience. It is not saved in the configuration; if a saved session
+is later used by a different user, that user's name will be used.
