This blog post is intended to notify all Windows Hardware program partners that Microsoft has taken a strategic initiative to clean up legacy drivers published on Windows Update to reduce security and compatibility risks. The rationale behind this initiative is to ensure that we have the optimal set of drivers on Windows Update that cater to a variety of hardware devices across the windows ecosystem, while making sure that Microsoft Windows security posture is not compromised. This initiative involves periodic cleanup of drivers from Windows Update, thereby resulting in some drivers not being offered to any systems in the ecosystem.
