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...

To update Windows 11 23H2 to 26H1. If you prefer a more manual and "challenging" approach, you can perform the upgrade entirely offline using official Microsoft update files.

Download the ISO from Microsoft: The most straightforward offline method is to get a Windows 11 ISO file that contains the version you want.

Use Microsoft Update Catalog: This is the official source for standalone update packages (.msu and .cab files). You can search for specific update Windows 11 23H2 to 26H1 for your system version and install them.

Install with DISM or PowerShell: If you want a truly command-line-driven experience, you can use the built-in Deployment Imaging Service and Management Tool (DISM) or PowerShell's Add-WindowsPackage to install these updates directly. These commands bypass the standard Windows Update service and allow you to inject the update directly into your system image.
