Addressing the assorted throngs in a Community Standup,  Kevin Gallo was chatting about the Windows 10 Fall Creators Update SDK, but words suddenly failed him when it came to ARM64 support for UWP.

"We have not announced support for that right now. It's something we're looking at and evaluating, but I have nothing to share right now."

There have been 64-bit ARM devices running Windows 10 Mobile since 2015 when Microsoft launched the Lumia 950 and 950 XL, but they all run a 32-bit version of the OS. Vole has previously said that 64 bit was not necessary because there are no Windows phones with more than 4GB RAM, which is fair enough.

However, with Windows on ARM coming, ARM-based PCs that can run x86 apps are going to be a thing.  Developers should be able to compile a UWP app in ARM64, as it would surely run better than an x86 app, or even an ARM32 app.

But with Windows on ARM PCs just a few months away, Microsoft won't confirm that support for ARM64 is even coming to the Windows 10 SDK. Vole should be looking at Windows Store submissions for ARM64 apps by now. 

Of course, this isn't to say that support isn't coming, but it certainly doesn't appear to be in the near future.
