New usage data from AdDuplex shows that the Creators Update is now used on about half of all Windows 10 PCs. But its deployment rate is much slower than that of its predecessor, the Anniversary Update.

As you may recall, AdDuplex bills itself as the largest cross-promotion network for Windows apps. AdDuplex 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 50 percent of all Windows 10 PCs. Usage of the most recent version of Windows 10, the Creators Update, or version 1703, continues to grow sharply. After hitting about 35 percent last month, the Creators Update is now in use in over half of all Windows 10 PCs, or about 50.1 percent.

Creators Update deployment is slower than that of the Anniversary Update. Though it was marred by numerous issues, the Anniversary Update actually rolled out quite quickly; in fact, at this point in its deployment, the Anniversary Update’s rollout actually picked up the pace dramatically. Not so with the Creators Update, which lags behind the 75 percent deployment rate of its predecessor at this point in time.

Microsoft is not “leading the way” when it comes to Creators Update deployment. You’d think that Microsoft’s Surface devices would be the very first to get each new update, but that hasn’t happened. Thanks largely to Surface Pro, especially Surface Pro 3, Microsoft’s devices are no better or worse than any other PC makers in this regard. Only 18 percent of Surface Pro 3s in the world are running the latest version of Windows 10. That is pathetic, sorry. Especially when you consider that…

Surface Pro 3 accounts for almost a quarter of all Surface devices in use. Yes, Surface Pro 4 is the most-used Surface device, with 41 percent of usage. But Surface Pro 3 is number two, at 24 percent.

Surface Laptop and new Surface Pro usage cools. After a quick start last month, usage growth of Surface Laptop and Surface Pro (2017) has declined sharply, with each growing just .2 percent. The party was fun while it lasted.
