If you don’t use the Public folders provided by Windows, you may want to remove the shortcuts. Most open/save file dialogs and Windows Explorer have a Favorite Links section that includes a shortcut to the Public folders. Plus it’s listed on the main folder list, along with shortcuts to the user’s folder and to the drives.
Removing the shortcut from the Favorite Links is easy. Just open your Links folder: C:\Users\username\Links. Then delete the Public.lnk.
Taking the shortcut off of the Folders List, however, requires a registry change. You need to delete the following registry key:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\
explorer\Desktop\NameSpace\{4336a54d-038b-4685-ab02-99bb52d3fb8b}
