The latest data shows that the Fall Creators Update now accounts for over 50 percent of all Windows 10 PCs in use.

This data, as always comes from AdDuplex. As you may recall, AdDuplex is 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’s new in Windows 10 PC usage this month.

Fall Creators Update usage surges. As you may recall, the Fall Creators Update accounted for just 20 percent of all Windows 10 PCs in use in late November. That number is way up a month later, with the FCU now accounting for 53.6 percent of all Windows 10 PC usage.

Fall Creators Update usage varies by countries. Western Europe, Canada, and the US lead the way, as you might expect, with roughly 60 percent usage for the FCU in both places. Africa and South America are at the rear.

HP, Lenovo, and ASUS PCs get getting the Fall Creators Update the quickest worldwide. AdDuplex notes that only three PC makers—-HP, Lenovo, and ASUS—-made the top-5 list in all the markets it surveyed. “HP is at the top almost everywhere except for Russia,” AdDuplex notes. “Dell is second in US and India, but only fifth in biggest European markets and not even in [the] top 5 in Russia.”
