Microsoft has announced what we have been expecting for some time:x64 app emulationis coming to Windows 10 on ARM PCs. The news came througha blog postfrom Microsoft’s Chief Product Officer, Panos Panay. The plan is to start rolling out the feature in November through the Windows Insider program, with a likely commercial rollout for Spring 2021.
Currently, Windows 10 on ARM laptops can only emulate 32-bit Windows apps in addition to running native apps compiled for ARM64. But many high-end applications and apps for enterprise rely on 64-bit-only editions, which are incompatible with ARM. That now changes and will open the gates for many more apps to run on devices likeSurface Pro X, SamsungGalaxy Book S, and LenovoFlex 5G.
There is no further detail on the limits and performance expectations of x64 emulation, but like 32-bit, it is likely to take a slight performance hit. Newer Windows 10 on ARM PCs with Qualcomm’s just-announcedSnapdragon 8cx Gen 2should help with that as that chip is faster and more efficient.
Besides the x64 emulation, Microsoft will “soon release a native Microsoft Teams client optimized for Windows 10 on ARM” – an issue wecomplained about last year. Back in July, Microsoft noted thatMicrosoft Teams for ARM64 was planned, but no further details were given. Now, at least, it seems we are much closer to that release happening. Microsoft Teams is a crucial app during this work-from-home shift, and devices with Windows 10 on ARM are becoming increasingly important to enterprise and business users. While Microsoft Teams currently runs on ARM PCs, the performance is not nearly as good a natively compiled app.
Microsoft also announced Visual Studio code has also been updated and optimized for Windows 10 on ARM.
The news around Windows on ARM has been building. A week ago, Microsoft announced itsApp Assure Program was expandingto support Qualcomm Snapdragon PCs. The program helps devs and businesses streamline, optimize, and fix apps brought to the Windows on ARM architecture.
Likewise, new Windows on ARM PCs are expected from Microsoft with a refreshedSurface Pro X, the new AcerSpin 7, and a newconvertible from HP

The thinnest and lightest Surface Pro available
Surface Pro X delivers the most exciting design for the Surface Pro yet. While the ARM processor is faster than expected for many casual users, a Surface Pro 7 will be a smarter buy. But for those who need a light, thin, LTE-enabled productivity laptop, the Surface Pro X offers a unique set of features not found anywhere else. It’s not a bad PC; it just needs the right owner.
