i can confirm you get shaders on update if you're running some intel graphics chip that couldn't do shaders before.
it is a pain in the ass to fix if you have bootup issues tho cause the os is so new there's barely any help articles.
protip:
during bootup, on that grey screen where the circles are just revolving around, you can ctrl-alt-delete to open up a temp screen if you're stuck there. from there, you can hit restart while holding shift, to open up the troubleshooting menu
basically if you can click "restart" while holding shift you'll be able to solve any basic startup issue, or open safe mode.
