Amplid,

You can try the uninstall option from the disk to see if it can cleanup anything that may be left over.

If you feel comfortable in the registry, you can also go to the registry and click on Edit and Find on the toolbar. Type in Call of Duty and click Find Next. Right click on anything that it finds related to Call of Duty and click Delete, then click on Edit and Find Next again. Repeat this until it does not find anything else on Call of Duty and is finished.

WARNING:
Be careful in the registry. Deleting the wrong key can result in the need to reinstall Vista.

Hope this helps,
Shawn
