ARM-based Windows 10 devices have improved in performance, but the software is another story -- without official tools to write native 64-bit ARM apps, it's been difficult to help these machines reach their potential. That shouldn't be an issue after this week. Microsoft has released Visual Studio 15.9, which gives developers the tools they need to craft native ARM64 apps. They can submit those apps to the Microsoft Store, too, although they can also release ARM apps elsewhere (or bundle them into releases for other chip architectures) if they'd prefer.
