Hi David Hespelt,
Welcome to Microsoft Q&A forum. I'm happy to help.
You should perform an In-place Upgrade or a Clean Install. An added benefit is that the image already includes Windows 11 25H2, so you won’t need to install any major updates.
Disclaimer: Let’s try performing an in-place install or in-place upgrade which will refresh your Windows files and operating system without removing files or applications. That being said, we always recommend that if you have important data, you should back it up before making large system changes. If you want to back up your data first, please do so. Once you are done backing up, you can follow the steps in the following guides: How to run In-place upgrade in Windows 11 - Microsoft Community
If you have any further questions or get trouble with any steps, please don't hesitate to let me know.
