"It seems pretty obvious that the Copilot+ PC brand hasn't resonated with the market, and OEMs and Microsoft itself are now quietly pulling back on that branding. The specification baseline for Copilot+ PC experiences still exists, it just no longer has a pretty marketing name tied to it.
The rough launch of Copilot+ PCs, paired with the fact that Microsoft Copilot itself doesn't have a very strong reputation these days, likely contributed to the decision to slowly retire the Copilot+ PC branding. The brand never made sense to me anyway... these PCs have nothing to do with Copilot."
