I have a suggestion here.But it needs a small work in the registry.
Back it up before editing the registry.
The entries in add\remove programs are stored in the following registry entry
for ex:If I want to delete the Nero Burning Rom from add remove list,I delete the following reg entry
Hkey_Local_Machine\Software\Microsoft\Windows\Current Version\Uninstall\Nero-Burning Rom!UninstallKey
once you delete it,it will be gone from add remove programs.
I used this tweak to change the picture and display name of some programs in add remove list.
It's a small and nice tweak.
But be careful in not deleting the programs wrongly.
Back up the registry before you do a work on it.
Hope this explains your question!
