Windows 7 - Guest account restrictions

I have turned on the Guest account, and I need to set program and folder access permissions. I have google'ed the way to set file and folder permissions, but I am having some difficulty with some of the things that I need.

For instance I need to:
-deny access (just deny listing the directory structure; can read & write so apps can work) to C:\* , Control Panel, and a few other locations

If I try to deny dir listing for Guest on root C: , it gives me a couple warnings and will not set permissions for "program files, program files x86, windows" folders even though I am the admin. After those initial issues, it continues to set the permissions for all the rest of the files. If I log into the guest now, goto Computer and double click on C: , it now says "access denied" -- which is good -- BUT -- if I type in the address bar up top "C:\users", it will goto that location; not display the access denied message. What am I missing?

Edit: I am using the Home Premium edition so I cannot use the Group Policy Editor..

This may be what you are looking for.
Permissions - Allow or Deny Users and Groups

I think you are going way to far. The guest account is already restricted on so many levels.
