Microsoft have announced x64 emulation is coming to Windows 10 on ARM. In November x64 emulation will be in available to test for Windows Insiders which should mean fast application and better battery performance of x64 apps. It is the missing piece of the puzzle for devices like the Surface Pro X. We should also see more ARM powered Windows devices coming soon.
We are excited about the momentum we are seeing from app partners embracing Windows 10 on ARM, taking advantage of the power and performance benefits of Qualcomm Snapdragon processors. We heard your feedback and are making Microsoft Edge faster while using less battery, and announced that we will soon release a native Microsoft Teams client optimized for Windows 10 on ARM. We will also expand support for running x64 apps, with x64 emulation starting to roll out to the Windows Insider Program in November. Because developers asked, Visual Studio code has also been updated and optimized for Windows 10 on ARM. For organizations, we’re committed to helping them ensure their apps work with Windows 10 and Microsoft 365 Apps on ARM64 devices with App Assure. We are working closely with Acer, HP, Lenovo, Samsung and Surface to bring these Windows 10 on ARM innovations and products to our shared customers.
