On the eve of Windows 10's next major feature update, the April 2018 Update appears to be topping out with an install base of nearly 90 percent of Windows 10 PCs. That's according to AdDuplex's latest monthly report, which pegs the Aprils 2018 Update's share of the Windows 10 market at 89.6 percent.
Based on AdDuplex's reports over the past several months, the April 2018 Update has been the fastest Windows 10 update to roll out to the public. The rollout surged up to around 78 percent of Windows 10 PCs in June but has slowed since. Compared to the August report, the update has shown nearly 3 percent growth in September.
When compared to other Windows 10 versions, the April 2018 Update continues to dwarf their share. The closest is, as you'd expect, the Fall Creators Update with 5.7 percent coverage. The Creators Update and Anniversary Update follow with 1.7 percent and 1.8 percent, respectively. Windows 10 versions 1511 and 1507 round things out at 0.6 percent and 0.3 percent, respectively.
As usual, it's best to use AdDuplex's numbers as a sort of general barometer for the rollout pace. The firm's numbers likely differ from real-world numbers, and this became apparent when Microsoft released its most recent official numbers, which differed quite a bit from AdDuplex's reporting at the time. This is likely due to AdDuplex's method of sampling data, which depends on a collection of around 5,000 Microsoft Store apps that take advantage of its SDK.
