Helped my dad do tech support for a doc office. Even simple stuff like glucose meters barely worked on windows 7, and broke with windows 10. The web portal they used required a specific version of internet explorer to function. I think the biggest issue is always going to be how slowly these devices work in terms of drivers and software compatibility. For security and cost reasons, I’d guess.
Yeah main thing is Ventoy and images for windows 10 and 11. I also have some basic tools, and some portable versions of some games I like (OoT, Warcraft 3, etc).
