If they’re rewriting Windows core bits with it, that’d seem a fairly strong indicator their involvement with it is serious. That’d be unnecessary technical debt otherwise. Windows on ARM is probably fine. Windows Phone and the like eventually lost (losing? I haven’t kept up) support, but phones are traditionally a 2ish year supported device and then they’re not targeted (specifically in the Android OEM arena). Windows proper they have business clients and if they don’t support it for a reasonable amount of time, Microsoft is basically hosed. It is, I imagine, why once they decided to kill off older IEs everything prior to latest and greatest was killed at the same time: they had supported them for far too long and it required killing them all Off in one move.
