October 2018 Update crosses just over 26 percent of Windows 10 PCs, AdDuplex says

Microsoft is largely expected to release its next major Windows 10 feature update in the coming weeks, but the previous release has only managed to break through a small portion of the market, according to the latest report from AdDuplex. During the month of March, AdDuplex reports that the Windows 10 October 2018 Update managed to reach 26.4 percent of Windows 10 PCs, jumping just over five percentage points from where it stood in February.

The Windows 10 April 2018 Update still retains the lion's share of the spread, coming in a 66.3 percent of Windows 10 PCs. Given that the October 2018 Update's launch issues and that it only reached full availability in December, it wasn't surprising to see a slower rollout than previous updates, but it's interesting that its share of the Windows 10 space remains so low compared to other updates at this point in their lifecycle.

Following up on the April 2018 Update is the Fall Creators Update with a 3.5 percent share, with PCs on the Creators Update and older making up a combined 3.4 percent share. Windows Insiders on the 19H1 preview builds take a 0.4 percent share.

As with all of AdDuplex's reports, it's worth noting that the data is based on a sample of 5,000 apps that use its SDK. The data was analyzed on March 26 from a survey of more than 100,000 PCs, AdDuplex says. Real figures likely differ, but AdDuplex's monthly reports are a useful tool for gathering a baseline for the spread of each update.
