Windows 11's 5GB monthly .msu updates, AI is only part of the problem

Windows 11 monthly updates are now regularly exceeding 4GB in size, with some reaching 5GB, due to a combination of AI-related components and structural inefficiencies in how updates are packaged. While AI features like semantic search contribute to the bloat, the primary issue lies in Microsoft's cumulative update model, which bundles all changes into a single large package for reliability and compatibility. Most home users download less thanks to delta updates and hardware-specific filtering, but enterprises face growing storage and distribution burdens. Without changes to how features are delivered or new update baselines, sizes are unlikely to shrink.
