Compatibility
Any use of a Microsoft logo to indicate compatibility must be pursuant to a logo license under one of Microsoft's Logo Programs:

You may use Microsoft trademarks in referential phrases such as "Works with Windows XP," "Runs on Windows 2000," and "For use with Xbox."
Do not use any Microsoft trademarks as your product name, service name, or company name.
Do not use product, service, or company names that could be confused with any Microsoft trademark.
Do not mimic or copy Microsoft's product packaging, advertising or trade dress.
Do not use Microsoft trademarks more prominently than your product or service name. You should maintain a visual distinction between your company and product name and any Microsoft trademark.
Do not create or use any logos that include a Microsoft trademark unless your use is pursuant to a license from Microsoft (for example, do not create your own Windows compatibility logo).

Logos
Do not use the Microsoft Corporate logo, Windows logo, or any other Microsoft logos, symbols, or icons on or in connection with products, packaging, manuals, promotional/advertising materials, or Web site for any purpose except pursuant to an express written trademark license from Microsoft.
