Windows 10 on ARM only supports emulating 32-bit X86 applications, which means that most desktop applications cannot run on this platform, which limits the development of this platform to a large extent.

In order to solve this problem, Microsoft released the X64 simulation preview program Build 21277 for ARM in the internal development channel.

Incompatible application

On the original Windows 10 on ARM devices, only native 32-bit and 64-bit ARM applications and simulated 32-bit X86 applications can be run, while the current mainstream 64-bit X86 applications cannot run on related devices.

However, Microsoft's new emulation program allows the current Windows 10 on ARM devices to run all programs normally, greatly improving the compatibility of the platform, and the competitiveness of the device itself will be further improved. This is undoubtedly very beneficial to the long-term development of Windows 10 on ARM.

In the preview version of the emulator, Windows 10 on ARM device users can install 64-bit applications, even key productivity applications, from the Microsoft Store and external addresses.

Programs that can run on Windows 10 on ARM devices with 32 bits can now reduce the consumption of memory resources.
