Worked on the MicrosoftDocs/azure-compute-docs repository to enhance documentation for VMSS OS image upgrades in Flexible orchestration mode. Focused on clarifying the automation of OS image upgrades, maintaining accurate image versioning, and detailing upgrade prerequisites and health monitoring steps. Updated the OS image table to include Windows Server 2025 images and outlined versioning requirements, ensuring users have clear guidance for managing upgrades. All documentation improvements were implemented using Markdown, leveraging Azure and cloud computing expertise. The updates also highlighted the preview status of Auto OS image upgrades for VMSS Flex, providing transparency and linking to relevant terms for users.
