Windows 7 gpo policy doen't work for windows 7 client

[marvel33]

Hi to all,
i have a windows 2003 active directory server and i configured the group policy setting "Remove user folder link from Start Menu" to enabled

This policy works correctly in the windows xp clients but doesn't work in the windows 7 clients; in the windows 7 clients i have yet the link to the user's folder in the start menu

Why? I have to do some additional configuration for windows 7 client?

Thanks
