There actually is a version of Windows 11 that exists without any bloat, AI or any other shit (most of the system requirements are also gone) called « Windows Iot LTSC », most of its updates are security ones, and for all I’ve observed it even escaped some of the crappy « windows killed itself » kinda updates. Any company can get access to it.

I don’t know if they use it, but they’d be dumb not to.
