> Hasn't the ISO to install W11 now gotten too large to be burned to the biggest DVD?

No.

The Windows 11 media creation tool still officially supports creating a DVD installer from ISO image for Windows 11 (including the latest 25H2 release), alongside USB drives etc. The requirements for the DVD version are still the same 8gb of space it has been for a while. As of today, the ISO is 7.2GB.

Virtually everyone uses a bootable USB thumbdrive or similar today though, and page you download the ISO from heavily encourages this, and is trivial to make with the Installation Media tool Microsoft give you.

You are right.

That wouldn't require a Blu-ray.

The ISO expands quite a bit after it is installed to your SSD.

Maybe they are backing up their whole systems to the Blu-rays?

Or have big movie collections which some comments indicated was expected.

I've used USB for a while, don't think I've even used a DVD to install Windows.

Did use them to back up years ago, but now a HDD for that.
