XP My Documents registry setting

Hey all,

Maybe this has already been discussed at some point, but does anyone know where the registry value for show/hide my documents is in XP?
I’ve checked numerous websites, and they all claim that the setting is a DWORD under HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\CLSID\{450D8FBA-AD25-11D0-98A8-0800361B1103}\ShellFolder . This is correct for 2000, but none of my XP workstations seem to take any notice of it.
Please advise.
