Microsoft’s May update package soared to 4.3GB! Whether you need it or not, you can force your 3GB AI file

Not long ago, Microsoft released the cumulative security update KB5058411 for Windows 11 24H2 and Windows Server 2025.

However, the size of this update is amazing, reaching an amazing 4368.9MB. In contrast, the size of the April update package KB5059087 is only 800 MB.

After investigation, it was found that the root of the problem was that Microsoft added a large number of AI-related files to the update.

Microsoft’s May update package soared to 4.3GB! Whether you need it or not, you can force your 3GB AI file.

According to the analysis of the user abbodi, the KB5058411 update file downloaded using 7-zip decompression will find that only about 850MB of files related to regular updates, and the remaining 3GB files are related to Microsoft’s AI application.

However, according to Microsoft, these AI functions are currently only related to Copilot+ PCs equipped with NPU, because AI functions are only planned to be installed and updated on these platforms.

Not only that, the update package is also provided to Windows Server 2025, and the practicality of AI functions in the server environment is obviously low.

This also means that although many users may not need these AI functions, they still have to download and install these huge files.

This situation reminds people of Microsoft’s plan to optimize the volume of updates proposed in November 2021, when Microsoft said that it would phase out old updates to improve download and installation speeds and enhance security.

But now Microsoft doesn’t care about packaging AI content into updated files, which seems to be getting further and further away from the previous goal.
