Despite being “fully available” to all customers, the Windows 10 Creators Update still lags behind its predecessor when it comes to real world usage. That’s according to the latest data from AdDuplex.

As you may recall, AdDuplex is the largest cross-promotion network for Windows apps. The company empowers developers and publishers to promote their apps for free by helping each other. And each month it provides a glimpse at which Windows devices people are actually using.

Here’s what we see this month.

Creators Update hits 66 percent of all Windows 10 PCs in use. Usage in the Creators Update has surged again in August, jumping from 50 percent usage a month ago to 65.6 percent.

But Creators Update usage still lags well behind the Anniversary Update. Microsoft announced in July 27 that it had made the Creators Update “fully available” to all customers. So it’s reasonable to assume that usage in this version would skyrocket. But despite this, usage in the Creators Update still lags well behind that of its predecessor at the same point in time post-release. A year ago, usage in the Anniversary Update had sailed past 75 percent at this point.

Windows Insiders barely register in the wider user base. Despite Microsoft claims of tens of millions of testers, Windows 10 PC running a Windows Insider build of the OS account for only .7 percent of all Windows 10 PCs. If you assume that Microsoft’s 500 million figure is still correct, that means that only 3.5 million PCs are actually running Insider builds. That’s less than half the number of Insiders.

Surface usage of the Creators Update did skyrocket, however. As you may recall, last month Surface Pro 3 was a weird outlier when it came to Creators Update usage, at less than 20 percent. This month, that changed nicely, and over 60 percent of Surface Pro 3s are now running the latest release. But it’s still the lowest among Surface models, including even Surface 3. About 80 percent of Surface Books are on the Creators Update, for example.

Surface Pro 4 continues to be Microsoft’s most-used device. Surface Pro 4 accounts for 43.6 percent of all Surface devices in use, but here’s the amazing bit: That’s actually a small increase of 1.4 percent over last month. Meanwhile, Surface Pro 3 (22.2 percent), Surface 3 (12.2 percent), and Surface Book (7 percent) round out the top five. Surface Laptop more than doubled its usage share to 1.4 percent, but that is much smaller than I expected. And the new Surface Pro now sits at 3.7 percent, well ahead of Surface Laptop (which is also unexpected). Surface Studio? O.0 percent. 🙂

HP is number one again overall. HP comes in at 24.9 percent usage, compared to 15.7 percent for Dell, 12.4 percent for Lenovo, 9.1 percent for ASUS, and 8.7 percent for Acer. Microsoft, meanwhile, manages just 2.6 percent usage, and arrives at 7th place, behind Toshiba. These numbers have not changed much in a few months, which is interesting.
