Proper use of Microsoft trademarks is important to us. The following guidelines were designed for OEMs, Resellers, and Distributors of Microsoft products. The common way to do this is to properly capitalize the product name and designate the trademarks with the appropriate symbols- or tm. You may also use underlining, italics, or bold type. Use Microsoft trademarks as proper adjectives.
Trademarks are adjectives that describe a specific brand of product.
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.
