In short, ISO files allow you to install the 25H2 update without Windows Update. The method is completely safe and very straightforward if you want to immediately explore the new features.

To download, you will need an Internet connection to retrieve the 25H2 update, which is approximately 7 GB. Although the ISO files have been available for download from the Insider platform, they are indeed a stable version. This is great news as you can install the update without fearing potential instability.

ISO files are usually available a few days or weeks before the deployment via Windows Update, which is considered a more user-friendly method. If you want to install Windows 11 25H2 right now, we have prepared a complete explanation below.
