Windows 10 on Arm no longer gets x64 app emulation

Microsoft started testing x64 emulation for Windows 10 on Arm almost a year ago, but the company now limits the feature to Windows 11. The planned feature allows x64 apps that have not been compiled for Arm-powered machines to run, allowing devices such as Surface Pro X to access even more apps.

“x64 emulation for Windows is now generally available in Windows 11,” reads an update to a Microsoft blog post today. “For those interested in experiencing this, a PC running Windows 11 on Arm is required.”

This means that if you tested the feature on Windows 10, it will no longer ship in future operating system updates. Instead, upgrade to a device like the Surface Pro X for Windows 11.

Microsoft says it’s still committed to “supporting customers on Windows 10 on Arm through October 14, 2025,” but the lack of x64 app emulation will certainly force many Qualcomm-powered hardware over to Windows 11.

Microsoft has not detailed why it has decided to drop x64 emulation on Windows 10 on Arm, but the company also announces that it is accelerating the rollout of Windows 11 faster than the company had previously expected. This means that even more devices will be eligible for the free upgrade, and hopefully more arm-powered.
