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.
The list is notable for the absence of many applications popular on Windows XP. Missing from the list include Adobe Systems's entire line of graphics and multimedia software, Symantec's security products, as well as the Mozilla's open-source Firefox Web browser, Skype's free voice-over-IP software, and the OpenOffice.org alternative to Microsoft Office.
Software that has been tested as part of Microsoft's Vista certification program to run on all 32- and 64-bit versions of Vista include CorelDraw and WordPerfect from Corel, PowerDVD from Cyberlink, Nero 7 Premium, Trend Micro AntiVirus and PC-Cillin, AutoCad 2008, QuickBooks 2007 from Intuit, Microsoft Office 2007 and many other Microsoft applications.
In addition, Google's Desktop Search and its Toolbar for Internet Explorer have earned Microsoft's approval.
