Hey do you remember this old thread:
http://forums.entropysink.com/showthread.php?t=273&highlight=WinCCWell I naive believed that this problem will be solved using some registry cleaner utillity. Now I know that this can be soved by deleting appropriate registry key
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\Explorer\MyComputer\Namespace
That's it, who knows maybe someone will find it useful
