I don't use Windows 7, but usually there is a way to add entries to your IME's dictionary. Unless you're going to typeset an Okinawan recipe book, you can always enter the characters word-by-word (or character-by-character) using other readings you know. In this case, your IME should have 高麗 as こうらい (or こま) and 胡椒 as こしょう, which is not too bad.
