It looks like Microsoft is working on 64-bit (x64) app emulation for Windows 10 on ARM PCs. The feature might be introduced in 2021, removing limitations on software use on ARM PCs.
If you're following Microsoft news, there's a chance you've already heard about Microsoft and Qualcomm partnering on bringing the full Windows 10 experience to ARM64 CPU-powered devices. This Windows edition will support running all UWP apps but will also introduce support for running x86 applications on devices with ARM processors. We haven't heard much about it since the first introduction back in December 2016, but Qualcomm officials have finally announced the date of arrival for the first bunch of devices with Windows on ARM64.
