Eh, with prebuilt PCs it’s muddy because the bulk of heavy lifting is done by Microsoft, not the manufacturer. It’s not unusual at all to pull up the firmware/drivers/etc page for a random laptop and find that updates stopped rolling out about 2 years after its introduction to the market, despite Reddit and similar being filled with reports of firmware bugs for that particular model.

Fair point, but I think the lack of those updates impacts the average consumer much less than lack of OS updates.
