Configure Advanced User Profile Properties only shows Profile of Current User?

[CallMeal]

I am trying to delete old user profiles from some Windows 7 based workstations in a specific OU. I am logged on as domain admin; However under advanced user profile settings, I only see one profile in the list, the one for the current user.
These are public computers, and I know the Do not display last user name policy is enabled. Would that cause profiles of other users to be hidden as well? If not, any ideas?
Thanks,

Still confused by this. Any ideas at all?

The profile list is stored in the registry under HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\ProfileList. The GUIDs are the built-in accounts e.g. S-1-5-18; the long ones are the domain accounts. If you click on each GUID node and look at the ProfileImagePath entry it will tell you path to the local profile and hence you can work out who it actually is. If someone has been messing around in the registry they can end up removing entries from the GUI.

To manually delete a profile you need to delete the GUID node and the folder under C:\Users
