Hi. I'm David, and I'm happy to help you.
Tiny Windows 11 is not an official Microsoft release. It is a community-created, scaled-down version of Windows 11 designed to run on hardware with limited storage or that is not supported. While it may reduce the installation size, downloading pre-modified ISOs from random websites presents risks. Microsoft does not support or endorse Tiny Windows 11.
The safest option is to download the official Windows 11 ISO from Microsoft.
