i think the info provided by the cab can help both of us:
Code:
*snip*
<characteristic type="HKLM\Security\Shell\StartInfo">
<parm name="HideSettings" value="0" datatype="integer" />
*snip*
so try to go to HKEY_LOCAL_MACHINE\Security\Shell\StartInfo and toggle HideSettings between 1 and 0
(be sure to soft reset afterward)
