Value I haven't seen documented anywhere (except some Japanese site):

In "My Network Places" to show "Add Network Place", "Network Setup Wizard" and "Wireless Network Setup Wizard":

CODE
REGEDIT4

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\Advanced]
"ShowWizardsTEST"=dword:1

[HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\Advanced]
"ShowWizardsTEST"=dword:1


If the value is 0 or not present, the wizards are not shown. Takes effect immediately, just press F5 to refresh.

Works on XP post-SP2, doesn't work on Server2003, I think I saw it on Vista (haven't stayed long enough to verify).
