The Redmond giant claimed to have nearly 1,000 global independent software vendors (ISVs) signed up to deliver a range of applications for the operating system.
Microsoft also promised to increase its efforts to help ISVs develop code that runs on Vista through a series of new partner programmes.
ISVs developing for Vista will deliver a range of software offerings, according to Microsoft, with 15 of the top 25 global ISVs among those creating applications.
Trend Micro was cited as one such developer. "Consumers and businesses are extremely concerned with keeping data safe from the multitude of online threats, " said Lane Bess, president of North America operations at Trend Micro.
Mike Sievert, corporate vice president of Windows Client Marketing at Microsoft, added: "A vibrant partner ecosystem encourages rapid and broad deployment of Vista, and enhances the great software experience that Vista delivers."
In a bid to woo ISVs Microsoft has also introduced several Vista application and developer readiness initiatives to help developers create applications that meet the 'Certified for Windows Vista' requirements.
Microsoft is also offering resources to help developers ensure that existing applications work with Vista. As part of these efforts, the company is making available a range of development, training and testing resources.
Partners building applications for Vista are promised access to technical support resources, Vista-based application testing and compatibility labs, community engagement programmes and Vista developer training and certification.
Among these initiatives is Project Glidepath, a community engagement programme for one- to three-person software development companies, known as MicroISVs.
Project Glidepath helps provide MicroISVs with the workflow-based guidance, sample code, content and technology needed to create successful applications for Vista.
