The term "hardcoded" refers to configuration that's imbedded in a program's code. To a programmer, it may have a negative connotation (if it is a bad design decision) and to a non-technical user, the term is probably too jargony.
For example, suppose Microsoft Word came with some templates hardcoded into the application. Users can use the hardcoded templates, but they can't modify them. These templates are tied to the version of Word installed too.
In end-user documentation, is there a better way to describe these templates than using the term "hardcoded templates"?
