According to the AdDuplex's latest monthly report, the Windows 10 April 2018 Update has reached 78.1 percent coverage of all Windows 10 PCs the firm has sampled. The surge continues a pattern that Microsoft has been on for a while, resulting in the April 2018 Update becoming the fastest feature update to roll out thus far.
For comparison, the April 2018 Update was at 50 percent coverage in AdDuplex's May report. The Fall Creators Update took twice as long to hit that mark after its release.
As for other feature updates, the Fall Creators Update now stands at 15.7 percent coverage, while the Creators Update is at 2.4 percent. The Anniversary Update, meanwhile, is currently at 2.5 percent, while Windows 10 versions 1511 and 1507 come in at 0.8 percent and 0.4 percent, respectively.
The extent of the rollout isn't too surprising; Microsoft confirmed earlier in June that the April 2018 Update had reached full availability. The company is also now more widely applying AI to its rollout process, resulting in a faster rollout than previous releases.
Still, there's a disparity between AdDuplex's numbers and what Microsoft has confirmed thus far. In announcing the April 2018 Update had reached full availability, Microsoft also revealed it had rolled out to more than 250 million devices, making it the fastest version to do so. Still, given Windows 10 is sitting at an install base of around 700 million devices, that's a far cry from the 78.1 percent coverage in AdDuplex's latest report.
The gap likely comes down to how AdDuplex samples data for its reports. The company is dependent on collecting data from around 5,000 Windows Store apps running its SDK, which could skew the results based on any number of factors.
