How to enable new features for Windows 11 September 2025 Update (KB5064081)

• The Windows 11 September 2025 Update (build 26100.5067, KB5064081) is rolling out for version 24H2 on September 9, 2025, with new features and security fixes.
• Since Microsoft enables changes gradually, you can manually unlock the new features by installing the update and running the ViVeTool command vivetool /enable /id:57048218 in Command Prompt as an administrator.
• This gives you access to Recall improvements, Lock screen widgets, File Explorer AI actions, and more.

The Windows 11 September 2025 Security Update for version 24H2 is rolling out on September 9, 2025, and you can manually force-enable most of the upcoming new changes. In this guide, I’ll show you how to complete this task.

Currently, Microsoft plans to release the September 2025 Security Update as build 26100.5067 (KB5064081) with some new features and security fixes. However, since Microsoft rolls out features gradually, not everyone gets them immediately. If you want early access, you can use the ViveTool (via @PhantomOfEarth) command-line utility to unlock the new features on your device. 

In this guide, I’ll outline the steps to enable (most) of the improvements introduced with the September 2025 Security Update for Windows 11.

FAQs about the Windows 11 September 2025 Update

If you still have questions about the September 2025 update for Windows 11, the following FAQs will help clarify what’s new and how to enable the latest features.

Will I enable all of the features by running the ViveTool command?

No, since some features are not available to everyone (even after running the ViveTool commands), and others are limited to specific regions.

Why do I need to run the ViveTool command to enable the new features?

You don’t have to use the ViveTool, but some people want to access the improvements as soon as possible.

The problem is that Microsoft rolls out new features gradually, even after they’re officially available. The idea is that if something breaks, the company can quickly stop the problem from spreading to more devices.
