The Windows 10 April 2018 Update is now on 89.6% of Windows 10 devices, an increase of just a few points from last month's 86.7%. The decreases are seen in older versions across the board, with the Fall Creators Update dropping from 7.8% to 5.7%, the Creators Update dropping from 1.9% to 1.7%, the Anniversary Update dropping from 2.1% to 1.8%, 1511 falling from 0.7% to 0.6%, and 1507 falling from 0.4% to 0.3%. The amount of Insiders, which includes both Redstone 5 and 19H1, remains stagnant at 0.4%.
While the Windows 10 April 2018 Update started out with a much faster rollout than the Fall Creators Update, it's never going to get over 90%, which the older update achieved. Very soon, the October 2018 Update will be available, and version 1803 will begin its decline.
What's probably most interesting this month is that the Surface Pro (2017) is now the second most popular Surface, overtaking the Pro 3. This chart hasn't changed in a meaningful way for some time, so this is significant. Surface Go share has more than doubled, from 1.24% to 2.54%.
