I think they're saying they're not using Windows to operate Artemis II but the astronauts are probably used to using Microsoft products. So when it comes to simple logging and data entry they probably are using Windows. But these are their own computers and not used to run Artemis II. I may be wrong but that's how I understood it.
Yup, sometimes it's too easy for me to just slip into work mode when talking about this kind of stuff and I don't elaborate enough. Thanks for stepping in.
Based on industry rumors I believe the Orion capsule control computers are running VxWorks (I've heard that maybe a few boxes are using RTEMS?) All of that source code would have been reviewed, audited, and tested to hell and back.
The day-in-the-life stuff for the astronauts is entirely believable to be Windows. The risk of it failing is so low (medium probability, low impact), it's what they'd be familiar with, and it's part of daily life at NASA anyways. Linux is no better when it comes to safety critical components and the astronauts almost certainly wouldn't want to be dealing with Gnome's... uniqueness....
