Starting processes under svchost.exe   

I noticed that sometimes WinWord.exe and iexplore.exe start under 
svchost.exe, specially when they are started by some of the microsoft 
products like Outlook and MSN Messenger. Just wondering what is the purpose 
of starting these processes under a system service rather than as a regular 
process? Anyone knows?

Thanks!
Joe
