Microsoft has released a set of six free tools for corporate users focused on assessment, planning, testing and deployment of Windows Vista.
The tools also include the latest release of Virtual PC 2007, Microsoft's virtualisation software for the desktop that includes special use rights for customers on Software Assurance maintenance programmes.
Delivery of the tools is part of an ongoing Microsoft strategy that began last year to provide migration tools as early as possible after the release of Vista, which shipped to corporate customers in November.
Migration tools released with beta versions of Vista in February 2006 were the earliest in an operating system development cycle that Microsoft made deployment tools available to corporate customers.
The company said its research showed some customers were spending up to $1,000 (£512) per desktop to migrate. Microsoft said its goal was to drop that cost below $100.
The six tools are: the Solution Accelerator for Business Desktop Deployment (BDD) 2007; Application Compatibility Toolkit (ACT) 5.0; Windows Vista Hardware Assessment 1.0; Microsoft Volume Activation 2.0 Tools; Key Management Service (KMS) for Windows Server 2003; and Virtual PC 2007.
