The tables in the "More Information" section list the products that currently have earned the "Certified for Windows Vista" logo or the "Works with Windows Vista" logo. There are many applications that are compatible and work well with Windows Vista but that are not listed in this article. This is because such applications have not yet gone through the Windows Vista logo program or are still going though this program. New applications are continually being added to the program. For the most up-to-date information about this program, run the Microsoft Application Compatibility Toolkit 5.0 or visit the Windows Marketplace Web site. You can also download the Windows Vista Upgrade Advisor to check individual computers.

The "Certified for Windows Vista" logo is a compatibility designation for applications and devices that have passed a rigorous testing program on computers that are running Windows Vista. The technical requirements for this designation target four core areas: reliability, security, compatibility with Windows Vista and future operating systems, and installation and removal. The "Works with Windows Vista" logo is a compatibility designation that is designed to encourage Windows Vista compatibility for the current generation of Windows-based applications. To receive this designation, software companies test their applications to make sure that the applications meet the program's guidelines.
