About Windows Messenger Services
- Windows Messenger is different from MSN Messenger.
- Windows Messenger comes with Office and XP; MSN Messenger is an external download.
- MSN Messenger has advertising displayed.
- Windows Messenger has a cleaner interface
- The only thing that MSN Messenger does that Windows Messenger can't do is logging of conversations. While I'd like chat logging, I don't want it badly enough to put up with advertising.
