Split Windows Live Messenger Cleaning

I wish to have two entries for Windows Live Messneger those are display pictures and anything else.

Since it's annoying to have no display pictures especially in sign in notifications.

But also leaving out the crap that messenger saves is annoying to (various content caches, and data of it's customer improvment program or something like that (sends usage data to microsoft))

You could just exclude the files you don't want deleted in Options>Exclude
