This tweak is useful for uncluttering your Control Panel and removing unused functions:
1. Open Regedit and go to:
2. Add a key named Don't Load
3. Next add String values within the "don't load" Key. You will use one String value for each control panel applet you want removed. For example, if I want to remove the System applet I will make a string value with the name sysdm.cpl and no value set and the System applet will no longer be available under the Control Panel.
4. To restore a full control Panel to default just delete the "don't load" key.
Here are the Windows XP Pro Control Panel applets:
