It wasn’t killing new versions of Windows, it was the decision to move to more of a rolling release model over the historical point releases which we saw as 10’s lifespan went on and still see in 11 with their “moments”. Specific Windows version was going to become less emphasized in favor of having a larger install base for the Store and whatever MS wants to do to that install base. And the big buyers of Windows were always volume sales too.

And then something changed, whether OEM’s complained, someone decided a change was necessary, etc. and boom, 11.
