Windows 10 version 1903 is now in use on over 45 percent of all Windows 10 PCs out in the world, according to the latest AdDuplex usage data.

“The growth of Windows 10 May [version] 1903 in September wasn’t as dramatic as it was in August,”
AdDuplex notes in its new report. “Still, it added more than 10 [percentage points] to its usage share.”

As you may recall, Windows 10 version 1903 usage tripled in August, to 33 percent. The big change this month is that it is, as predicted, now the most-often used version of Windows 10.  Window 10 version 1809 is in second place with 25.5 percent usage, followed by Windows 10 version 1803, with 24 percent.

As AdDuplex also notes, Windows 10 version 1903’s biggest gains this month came from Windows 10 version 1803 users upgrading to the latest version.

Additionally, AdDuplex takes a quick look at Surface PC usage just ahead of next week’s launch event for new models. Surface Pro 4 remains the most often-used Surface PC with 21 percent usage, followed by Surface Pro (2017) (16.3 percent), Surface Pro 3 (12.9 percent), and Surface Go (12.3 percent). This order hasn’t changed since AdDuplex last looked at Surface, back in February.
