You can prevent individual Control Panel components from loading underWindows NT versions 3.1 and 3.5 by modifying the Registry. However, thisdoes not work in Windows NT version 3.5. For example, if you modify theRegistry to specify that the Control Panel Keyboard component should notload, the component still loads.
In Windows NT version 3.5, a cache mechanism is implemented to speed upthe loading of Control Panel components. When you run Control Panel forthe first time, a cache is created that includes information regardingeach component in the Control Panel. Therefore, Registry entries specifyingcertain components not to load are not read in Windows NT version 3.5.
To work around this problem, add the /CACHE switch to the Control PanelCommand Line in the Program Manager Program Item Properties dialog boxafter you modify the Registry. For example:
Microsoft has confirmed this to be a problem in Windows NT version 3.5.We are researching this problem and will post new information here inthe Microsoft Knowledge Base as it becomes available.
You can use the following procedure to prevent Control Panel componentsfrom loading.
WARNING: Using Registry Editor incorrectly can cause serious, system-wideproblems that may require you to reinstall Windows NT to correct them.Microsoft cannot guarantee that any problems resulting from the use ofRegistry Editor can be solved. Use this tool at your own risk.
Run Registry Editor (REGEDT32.EXE).
From the HKEY_CURRENT_USER subtree, go to the following key:
From the Edit menu, choose Add Key.
Type "Don't Load" (without the quotation marks) in the Key Name text box and choose OK.
Select Don't Load.
From the Edit menu, choose Add Value.
Type the following in the appropriate text boxes:
Value Name: <Control Panel component> Data Type: REG_SZ String: 0 or 1 (Either string value will prevent the Control component from loading) The default Control Panel component names are: Color International Desktop Fonts System Keyboard Ports Date/Time Printers Mouse Network Devices Drivers Sound Cursors Server Services UPS Display (Windows NT version 3.5 only) MIDI Mapper (Windows NT version 3.1 only)
Quit Registry Editor and restart Control Panel.
NOTE: If you need to modify the Registry again to prevent additionalControl Panel components from loading, do not repeat steps three and four.
