How to clear msn contact list?

Wow Notherly what a pointless answer. Just had to point that out.





But I remember using a program what prunes msn contacts list. But I don't know if pruning is what you want. Pruning clears your whole list after a selected amount of minutes/days/weeks/months/years. If I find the program i'll email it to you.





Thanks and I hope i helped!





EDIT: Lol at your additional details.How to clear msn contact list?
1.right click on the contact name


2.a little menu will pop, select the last one that says delete contact


3.then it will ask you if u want to block that contact ( option ) and if u want to delete it from your windows live hotmail contacts


3.after you deleted that contact go to the bottom and delete it again from NON- INSTANT MESSAGING CONTACTS
Your own fault for having 900 contacts.
