Developed Windows support for the checkmake package within the mason-org/mason-registry repository, focusing on cross-platform development and package management. The work involved integrating ARM64 and x64 binaries, enabling seamless installation and runtime for Windows users. By leveraging YAML for configuration and registry packaging flows, the implementation ensured parity with other operating systems and reduced setup friction for developers and CI environments. This feature expanded the potential user base and aligned with the broader product roadmap, enhancing the overall user experience by streamlining Windows installations and supporting both major Windows architectures without introducing new bugs during the development period.
