it works on my machine, only caveats are the lack of a microsoft store (which doesnt apply to some people, including me) and the lack of an image viewer (easily fixed)
hell, i installed steam and it works fine. i don't get any weird errors and everything seems to function. i did install the xbox app manually (to stream my xbox to my pc) and even that one works, although it complains about the lack of an MS store sometimes.
LTSC is not what you think it is, it's like 10 with stuff stripped out instead of a completely minimal embedded OS.
Is this you?
