XP has a Setup Information file that controls what appears in the Windows Component Wizard. If you edit this file, you can remove these components as you would any others.
To start, use Notepad or another text editor to open the Setup Information file, sysoc.inf, which is generally found in the \WINDOWS\INF folder. Look for the line describing the program that you want to uninstall. Lines in the file have the format:
program=dll.inf entry, OcEntry, program.inf entry, numeral
Programs that are uninstallable all have the word hide or HIDE embedded in the string. Next, delete the word hide from the entry that refers to the component that you want to remove. For example, if you wanted to remove Pinball, you'd edit its entry by changing
Pinball=ocgen.dll,OcEntry,pinball.inf,HIDE,7
to
Pinball=ocgen.dll,OcEntry,pinball.inf,,7
Save the sysoc.inf file, then run the Windows Component Wizard by choosing Add or Remove Programs from Control Panel, and clicking on Add/Remove Windows Components. The component will now show up in the wizard. Remove it as you would any other component.
