Windows 10 on Arm x64 emulation goes live for Windows Insiders
Microsoft may have been first to port its Windows operating system to Arm-based devices back in 2017, but it is Apple that has grabbed all the headlines following the spectacular debut of its custom M1 Arm-based Macs in recent weeks. Windows 10 on Arm, however, was first to highlight the benefits of switching to Arm with outstanding battery life being one of the headlining features. The Samsung Galaxy Book S with Qualcomm Snapdragon 8cx launched earlier this year and delivered well over 20 hours of battery life in our testing.
While Apple has built the highly effective Rosetta 2 translation later into macOS to ensure seamless support for x86-based 32-bit and 64-bit apps on the Mac, Microsoft has been lagging behind in this regard on Windows 10 on Arm. That is slowly starting to change with the announcement that its long-awaited support for 64-bit x86 apps on Arm chips is finally in preview for Windows Insiders. Microsoft says x64 productivity apps like Autodesk Sketchbook and games like Rocket League should work and users can install x64 apps from a source of their choosing.
Microsoft’s blog outlines the directions on how to install the new build on devices including the Samsung Galaxy Book S, the Surface Pro X and the Lenovo Flex 5G. The company also says that x64 apps will work better with higher levels of RAM, which isn’t surprising. The only problem is that most Windows on Arm devices only support up to 16 GB of RAM at present, which means that if you really need to run an x64 app with less than that, you may have to skip multitasking. Better still, the company says it is working hard with developers to get them to recompile their x86 apps for Arm-64.
