How can I update Windows 11 23H2 to 26H2 or 26H1 now?

I am currently running Windows 11 version 23H2 and would like to know if there is a reliable way to upgrade to either 26H1 or 26H2 right now, as I have not seen these versions appear in my Windows Up...

Keeping Windows updated to a newer version can sometimes be difficult when Windows Update does not offer the latest build directly. In that situation, users may look for alternative ways to download official installation files and create their own update media. This can be useful for tasks like update Windows 11 23H2 to 26H1.

UUP Dump is a web-based tool that collects Windows Update files and allows users to create ISO images from official update packages. After selecting the desired Windows version, language, and edition, it generates a download script that can be used to build an installation image.

The general process is to choose the target build, download the package files, run the provided script, and wait for the ISO creation to finish. The generated ISO can then be used for upgrading or reinstalling Windows. For users who want to update Windows 11 23H2 to 26H1, this provides another way to access newer builds.
