Windows 11 25h2 ISO download for making an offline installer

Need to repair a Windows 11 PC and want to create an offline installer for Windows 11 25H2 and the official ISO would be the way to go.

The goal is to have a clean, legitimate copy that can be used to make a bootable USB drive or DVD for fresh installs on machines without a reliable internet connection. Microsoft's official download page is the obvious first stop, but it's not always clear whether 25H2 is available there yet or whether the Media Creation Tool is the better route.

Would love to know the safest and most straightforward way to download the official Windows 11 25h2 ISO offline installer?

Thanks in advance!
