Info on Windows 10 update KB4033637 finally released by Microsoft

A few weeks ago, Microsoft released a mysterious update KB4033637 for Windows 10 version 1607 (Anniversary Update). The update was just pushed to users, without a knowledge base article to provide additional info about the release.

That left users wondering what the update is about. Because changes these updates bring are not visible on the first sight. In fact, users barely notice any changes after installing a KB update. Unless that update causes some issues, of course.

And now, Microsoft finally released some additional info about the update, to put users’ confusion to end. You can now find the update on Microsoft’s support page, where the article describes what the update brings.

Users were speculating a lot about what’s the purpose of this update, and as it turns out, it’s not what they expected. Here’s what Microsoft says about KB4033637:

“This update includes diagnostic and functional improvements for determining the applicability of updates in Windows 10 Version 1607. The files and resources in this update ensure that feature updates are installed seamlessly to improve the reliability and security of Windows 10.”

Since the update was released mid-July, you probably already have it installed on your computer. And now you know what it does. We imagine it’s not what users expected exactly, based on previous discussions.

Also, we’ve seen a lot of complaints from users who installed KB4033637, as they’ve been reporting various issues since it came out. It’s quite frustrating for users to encounter problems from an update they don’t know anything about.
