Windows 7 Customize Navigation Panel

Hello does anybody know how to hide or maybe delete some of these User folders in the navigation panel?

-Searches
-Contacts
-Desktop
-Favorites
-Links

All of these folders are located in C:\Users\Username, i've tried to assign them as hiden atribute but they are still visible in the navigation panel. I've read in some other thread in this site that someone move the content of some of those folders to another location, but i've screwed up the system and have to restore windows. Thanks

Thanks for your reply, but thats not what im looking for. What im trying to hide or delete if possible are those folders inside the user root C:\Users\Username. They are useless in my case but maybe windows needs them for some reason
