Last month Microsoft removed the throttle that was limiting the rollout of the Creators Update, opening it up to every compatible machine. As a result, penetration of this latest version of Windows has gone from 50 percent to 65 percent, according to the numbers provided by AdDuplex.

With the Fall Creators Update due next month, at this point it seems likely that the deployment of the Creators Update won't be complete by the time the Fall Creators Update is released. This is a slower pace than the previous major update, the Anniversary Update. That was first released in July last year, and five months later it was at about 86-percent penetration.
