Hi,
1. Some very old applications which made use of Messenger API require Windows Messenger to
exist or they'll freeze up. I can't even think any that weren't fixed in this regard. That
and of course Remote Assistance, App Sharing and Whiteboard as previously mentioned in
Windows Live Messenger. Delete the folder if you want.
2. You can grab it again from the Microsoft Download Center or Windows Update.
3. MSN Messenger is a component of MSN 8/9 (aka MSN Explorer), which is what that folder is.
If you're not using this, then you can delete it. If you are using it, don't bother deleting
it as it will just re-download Messenger again the next time it's used. I usually just
delete this entire \Program Files\MSN folder as it serves no real purpose if you don't use
MSN Explorer.
