Windows 11 updates have grown significantly in recent years and today often reach between 4 – 9 GB. In the past, the same updates were many times smaller, but changes in the way of development and distribution have led to packages becoming significantly larger and excessively bulky.
One of the main reasons for the growth in size is the integration of AI functions. Microsoft includes components for advanced functions in each package, although many computers do not use them at all. During the installation, the system checks what is really needed, so it often uses only a part of the several gigabytes downloaded, while the rest remains unused.
Windows 11 Updates – AI, Cumulative Model and Delivery Cycle Increase Size
Another key factor is the cumulative update model. Each new monthly update contains all previous updates, so that the system remains secure even if some earlier updates have been skipped. This approach increases stability, but directly affects the size of the package, because the amount of data is constantly increasing.
Microsoft tried to alleviate the problem by introducing so-called “checkpoints” points in the Windows 11 24H2 version, but the spaces between them became too large, so the optimization effect is not significant.
The third reason is the fixed monthly update delivery cycle. Unlike Apple’s approach, which releases updates when they’re ready, Microsoft uses a strictly defined schedule. This often leads to grouping a large number of changes into one package, instead of more frequent and smaller updates.
Users can check the amount of downloaded data through system options:
Settings > Windows Update > Advanced options > Delivery Optimization > Activity monitor
Here it is possible to see how much data comes directly from the Microsoft server, and how much from the local network or cache.
The combination of AI features, a cumulative model, and a fixed schedule make it clear why Windows updates continue to grow, and why that trend won’t change anytime soon, explains PCWorld.
