A few days ago, Davuluri shared his excitement about it on his official X handle. He seemed very eager to reveal what the company has in mind at the upcoming Ignite event regarding the agentic OS plans.
Unfortunately for Microsoft and Davuluri, the response has been overwhelmingly negative, so much so that the comments on that X post have now been disabled.
Made me laugh. :)
And IIRC you xan choose to just keep it (so install it) right from there.
You can also load it up, and then do wild stuff and install, upgrade things (which will disappear ofc.).
That USB boot is crazy cool if you think about it IMO.
