We're still waiting for the next Windows 10 update, probably to be named the April 2018 Update, even though April is rapidly nearing its end. This means that the Fall Creators Update, Windows 10 version 1709, is still the latest update, and hence, it's still creeping upward in usage.

This month, according to the numbers collected by AdDuplex, the Fall Creators Update was found on 92.8 percent of Windows 10 installations, adding another two percent over last month. That makes it the most widely used update yet: the Anniversary Update (version 1607) peaked at 92.1 percent after eight months of availability.
