>Windows PC/laptop though.

needs to be noted that it's increasingly uncommon to be able to do so. for desktops you have to build everything yourself - prebuilds (either gaming or workstations) have proprietary PSU and motherboards (in case of workstations, sometimes CPU is bound to the motherboard / manufacturer, for example Threadrippers). Windows laptops now often come with soldered RAM and soon will probably be without M.2 slots like Macs.

There is Framework though I guess

Well my PC is built on my own and I change parts every year or two. My laptop is a Thinkpad from last year and Im pretty sure I can easily open it to replace something just like my last one.

Right, that was a rhetorical question, highlighting the fact that such an occurrence is even possible, to such a degree of incidence that I know multiple people who have experienced it. Meanwhile, never once heard an anecdote about a MacOS update (though I can imagine it has happened to someone out there, just never heard about it-- in contrast to numerous news articles about Windows' frequently-destructive updates)
