Uninstalled crappy 30 day freebies.

But the icons (albeit skeletons) remain in the Welcome Center.

Right click does not work.
Do not wish to go into the registry and delete these icons.

Anyone have a solution?

The only info I can find suggests the follow edit:

This is driven by the xml file in:

%SystemRoot%\system32\oem\info\...\oobe.xml

You should consider editing this file to be like editing the registry.

The format is fairly self-explanatory, however be careful not to change the xml namespaces.
