As you may recall, Microsoft released the Anniversary Update for Windows 10 back in early August, and those who do perform the upgrade will see that the OS has been upgraded to version 1607. For the first few weeks of availability, there was little indication that anything was wrong—a strange freeze issue notwithstanding—but then the problems started. (Microsoft finally fixed those freezes issues weeks later.)
At that point, Windows 10 version 1607 was running on just 16.2 percent of Windows 10-based PCs. It September, it nearly doubled, to 35.5 percent. And this month, it did so again, hitting 77 percent. So it’s reasonable to think that the Anniversary Update will indeed be fully deployed by the end of November. That doesn’t mean 100 percent, of course: Some businesses will stick with earlier versions for whatever reason. But it means, I think, that the problems are finally behind us.
