How to Prevent a User from Changing the User Profile Type

MORE INFORMATION

User profile settings are stored in the registry under the following registry key:

   HKEY_LOCAL_MACHINE\Software\Microsoft\Windows
      NT\CurrentVersion\ProfileList
				

For every user ever logged on to a Windows NT 4.0 system there is a subkey named after the security ID (SID) of that user where the actual values are stored. The user profile type is stored in the State value under the users subkey. Setting this value using system policies is possible but it does not prevent the System icon from Control Panel from appearing and therefore the user can change the profile type once logged on. Another disadvantage of changing the profile type in the registry is that you must ensure that you change the value in the subkey associated with the user. This implies that you must find the appropriate SID for the user.
