The responsibility for protecting trademarks occurs every time each trademark is used by Microsoft employees and our licensees-whether the trademarks are used in products, presentations, books, marketing materials, or advertisements. Correct use of our trademarks is important to Microsoft, so we've drafted the following guidelines. Set trademarks apart from other words or the nouns they modify. You can also use underlining, italics, or bold type. Use Microsoft trademarks as proper adjectives.
Trademarks are adjectives that describe a specific person, place, or thing.
Because a trademark is an adjective, use it with the noun that it modifies. In the case of our Windows trademark, follow the correct example below. Trademarks serve to identify the source of a product. If Microsoft trademarks are combined with the trademarks or product names of others, consumers may be confused as to which company is the source of a product. Don't use Microsoft trademarks in the possessive or plural form.
