Microsoft Baseline Configuration Analyzer 2.0 (MBCA 2.0) can help you maintain optimal system configuration by analyzing configurations of your computers against a predefined set of best practices, and reporting results of the analyses. Best practices are developed by a product development team or domain experts, and are packaged in the form of a best practice model. Models are available as separately-downloadable packages that can be run and analyzed by MBCA. MBCA lets users work with best practice models in a consistent, user-friendly way.
