This element deployed by Microsoft could finally boost Windows 11 ARM

Microsoft announced the rollout of ARM64EC support on Windows 11 ARM. This novelty should, we hope, encourage developers to better optimize their applications for the OS, thus making it more efficient.

It is done. Microsoft has rolled out support for ARM64EC on Windows 11 ARM. This new feature allows applications to operate in a hybrid way, combining ARM code running natively, and x64 code running through emulation. It is thus possible to run most of an application on ARM code, in native mode, while emulating in x64 certain specific extensions or functionalities.

For Windows 11 ARM, the addition of this support looks messianic since it will allow developers to gradually and more easily migrate their applications to the ARM architecture, but immediately benefit from a real benefit in terms of performance, highlights Windows Central. And if the two cases are not quite identical, this solution generally allows Microsoft to offer developers a tool similar to Rosetta 2, the ARM conversion utility launched by Apple with the first Macs under M1 processors.

A tool that could help boost the attractiveness of Windows 11 ARM

With ARM64EC, you can choose to start small and build incrementally. You can identify a part of your code base that would benefit the most from native performance and rebuild it in ARM64ECMicrosoft explains in a developer blog post.

The rest of the application will remain fully functional as emulated x64 code, but the recompiled ARM64EC parts will now have native speed. Over time, you can recompile more of the application to ARM64EC to further improve performance and preserve battery life for your application clients.“.

By deploying support for ARM64EC on Windows 11 ARM, Microsoft hopes to significantly increase the attractiveness of its OS to developers. This conversion method offers developers a concrete solution to make the conversion of their apps to ARM profitable much more quickly.

It should therefore encourage more developers and publishers to create or modify applications that correctly exploit the ARM chips used in particular by Always connected PCs or on certain devices such as the Surface Pro X. From there to imagine that Microsoft will soon catch up on Apple, there is only one step.
