The only way I know is by editing the registry, it might be something in
group policies in XP Pro though.
Open your registry and find or create the key below.
Create a new DWORD value, or modify the existing value, called "NoDispCPL"
and set it according to the value data below.
Example:-
User Key:
[HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\
System]
System Key:
[HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Policies\
System]
Value Name: NoDispCPL
Data Type: REG_DWORD (DWORD Value)
Value Data: (0 = disabled, 1 = enabled)
Exit your registry, you may need to restart or log out of Windows for the
change to take effect.
Note you can save the registry key first by:
On the File menu, click Export.
In the File name box, type SaveKey, and then click Save.
Or create a system restore point prior to editing.
Note: If the registry key is not there, you can simply create one by going
edit > new.
