To deliver on our customers' growing needs to create on the go with PCs with cellular connectivity, power-efficient battery life, and flexible designs, we announced today Windows 10 is coming to ARM through our partnership with Qualcomm.

Calling them "cellular PCs", Microsoft has managed to get the x86 code for the Windows 10 OS running on the ARM architecture — a phenomenal technological achievement. Microsoft Executive Vice President Terry Myerson revealed the news at WinHEC, and shared on the Windows Blog:

Microsoft just dropped a tech bombshell in Shenzhen, China, at the 2016 WinHEC conference: Windows 10 for PC – the full desktop version – is coming to mobile ARM processors in 2017.

The hardware required for Windows 10 on ARM starts with the recently announced Qualcomm Snapdragon 835 flagship SoC based on the 10nm FinFET process.

The new Snapdragon 835, which is already in production and expected in devices sometime in early 2017, features 27% higher performance while drawing 40% less power than the previous 14nm Snapdragon 820/821 SoCs.

The new silicon also features Quick Charge 4.0 tech, allowing for a five-minute charge to be enough for 4-5 hours of life for a phone, and up to 50% in 15 minutes.

Myerson made a point to tout the benefits of Windows 10 on ARM:

Hardware partners will be able to build a range of new thin, lightweight, power-efficient and always-connected Windows 10 PCs that run x86 Win32 and universal Windows apps

Full Access: x86 Win32 apps through emulation

It's not just the OS: Windows 10 on ARM will also run traditional x86 Win32 apps and games through emulation.

Users will be able to install any x86 Win32 app – unmodified – from any source, no repackaging as UWP or delivery via the Windows Store required. The apps are not sandboxed and they will have full access to the OS. Apple made a similar emulation feature when the Mac line switched from PowerPC to Intel processors, but Microsoft's move to support ARM is a magnitude more impressive.

To prove the power of the Snapdragon 835, Microsoft demoed a device easily running the full Adobe Photoshop app along with Microsoft Office. It's not just for apps either — the popular MMOG World of Tanks was demonstrated on stage being powered by ARM and Windows 10.
