  • Originally, Windows 10 (not the mobile version) could run only on PCs that were powered by x86 and x64 processors. From 2018, Windows 10 desktop could run on machines that are powered by ARM64 processors with the Fall Creators Update or newer.
  • Windows 10 is going to take another step in the ARM lore. Recently, we have been provided with evidence to suggest that Microsoft is close to enabling the execution of Windows 10 64-bit code on ARM laptops.

Microsoft will bring 64-bit code to ARM devices

Well, now it seems like Windows 10 is going to take another step in the ARM lore. Recently, we have been provided with evidence to suggest that Microsoft is close to enabling the execution of Windows 10 64-bit code on ARM laptops.
Right now, ARM laptops use the WoW emulator for running Win32 code on x64 computers to run Win32 code on ARM64 code. It’s a way to go around the fact that 64bit Windows applications are not supported on Windows 10 ARM laptops.

ARM64EC will emulate on ARM64 machines

The evidence explicitly mentions support for x64 code emulation on ARM64 from a recent GitHub commit.

It seems like the architecture will be named ARM64EC, for x64_64 on ARM64 machine types. The commit was made by Kenny Kerr, Engineer on the Windows team at Microsoft.

Although the name can be changed ten times before release and we don’t have even an approximate launch date, this is great news for ARM computers, low voltage computing in general, and, why not, Windows 10 to be adopted in full swing even on low powered devices.
