remove key Start_ShowNetPlaces, different result

[SarahNian]

I have assigned 3 users in windows XP.

under user1, I remove registry key Start_ShowNetPlaces. Network place appear in start menu.

However, when I do it as well under user2 and user3, Network place disappear in start menu.

I check another related key NoStartMenuNetworkPlaces, but they are same. Does there any key else

impact such result?
