Microsoft ARM bringing x64 App Emulation to Windows on PC

Microsoft has finally revealed that support for x64 emulation for Windows is coming on ARM. Right now, Windows can run native 32-bit ARM and 64-bit ARM apps on ARM devices, but they can only emulate x86-32 apps. This means that devices such as Microsoft Surface Pro X are unable to run many existing apps built for Windows 10.

The addition of x64 App Emission for Windows on ARM will open a variety of new possibilities and close the App Gap problem, as a lot of modern Windows apps no longer support x86-32. Microsoft makes it clear that x64 emulation is coming on all Windows on ARM devices, even devices running on the platform are as old as Qualcomm Snapdragon 835. Of course, emulated apps will not perform as well as native apps, but the option is simply unable to run the application.

Microsoft said the new x64 emulation support will be available to users on the Windows Insider program for the first time in November, with widespread availability continuing for some time each year.

Over the past several months, Microsoft has worked to beef up Windows on the experience of ARM, working to bring Xbox game streaming to users. The company announced a collaboration with Qualcomm to improve app compatibility for Windows 10 on ARM PCs and to extend the App Assurance program to cover Windows 10 on ARM64 PCs.

Today’s announcement can predict the arrival of the new Surface Pro X device, which has been rumored as recently as this month. If the reports come true, the device will feature the company’s latest Surface SQ2 processor, which may be based on Qualcomm’s Snapdragon 8cx Gen 2 5G, and launch in October.

As part of today’s announcement, the company also stated that it is accelerating Microsoft Edge using less battery, and will soon release a native Microsoft Team client that is optimized for Windows 10 on ARM.
