Microsoft does not give an official option to install Windows 11 without AI. However, after installing it, you can try a few steps to turn off or disable some AI features. Keep in mind, some AI is built into the system and cannot be fully removed. Also, future updates may bring in more AI, since Microsoft is moving toward adding more AI features, not fewer.
