Microsoft points to a transition of Windows 10 Mobile to 64-bit

From PC World: There's a lot to like in Microsoft's Windows 10 Mobile for smartphones, but it has one glaring weakness: It still is a 32-bit OS.

But a transition to 64-bit for the OS was inevitable as memory capacity in smartphones goes up, Microsoft said during a presentation at the Ignite conference last week.

Windows 10 Mobile lags behind Apple's iOS and Google's Android, which transitioned to 64 bits a few years ago. Many new Windows phones already have 64-bit ARM-based Qualcomm processors, but the OS still runs as 32 bit.

Thirty-two bits is "not really a limitation for us since the devices are all 4GB [of RAM] or less. But that will change over the next couple of years," said Jason Whitehorn, partner software engineer manager of the Windows and Devices Group at Microsoft.

The company is "very aware of" the impending transition and recognizes the importance of 64-bit, Whitehorn said.
