Go into the windows folder and then into the inf folder. Find and make a backup of the file sysoc.inf.
Now open the file in notepad.
Look for all the lines like this one that have the hide word near the end (it may be in capitals but that doesn't matter)
WBEM=ocgen.dll,OcEntry,wbemoc.inf,hide,7
Now change all the line like that by removing the hide word so it looks like this
WBEM=ocgen.dll,OcEntry,wbemoc.inf,,7
Save the file (please make sure you made a backup first). Now go into the Add/Remove applet in control panel. Go into Add/Remove Windows Components and you should see a whole bunch of extra things that you can add or remove.
Make any changes you want. Then once you are done un/installing them copy the backup file back over the edited one.
