Change my component GUID in wix?

Question

When should I change or not change my component GUID in WIX? The Microsoft SDK information is confusing.

Have a look at the WiX Tutorial, The Files Inside, for a detailed explanation on component rules. Basically, it says you never change the GUID of a component, since that means orphaning the old component and creating a new component.
