Here at Ars, we’ve been around long enough to chronicle every single time that Microsoft has tried to get Windows running on Arm-based processors, instead of the Intel and AMD-made x86 chips that have been synonymous with Windows for more than three decades. The most significant attempts happened in 2012 with Windows RT, which looked like Windows 8 but couldn’t run any x86 Windows apps; and in 2017 when Windows 10 Arm PCs arrived with rudimentary x86 emulation.

The main PC company backing each of those Arm efforts was Microsoft itself, which launched the original Surface to showcase Windows RT and the first Surface Pro X during the Windows 10 era. Since then, Microsoft has periodically refreshed the Arm version of the Surface tablet while continuing to sell Intel versions. A couple of PC OEMs put out Windows RT tablets, and most of them took a stab at one or two Windows 10-into-11-era Arm PCs. But there was never a big unified push that made it clear that the entire consumer PC ecosystem had bought into Arm.

This week’s announcements felt different—yes, there was a new Surface Pro and Surface Laptop from Microsoft leading the charge (and the new Surface Pro is the first Surface Pro ever to ship Arm as the default option for most people). But the Surface launch was accompanied by a major wave of systems from essentially every major PC OEM, suggesting at least some level of elevated enthusiasm for the Snapdragon X series that didn’t exist for older Arm chips.
