Microsoft Office to support ARM64 platform with Windows 11. Microsoft recently announced the next version of its operating system, Windows 11. The redesigned Windows introduced many new features such as support for Android apps with Amazon Appstore. Native apps are likely to be more efficient and deliver better performance than emulation.

In a blog post, Microsoft announced that Microsoft Office will support the ARM64 platform with the recently announced next version of Windows. Microsoft partnered with Qualcomm to develop windows and ARM developer PC in May earlier this year for developers. The aim was to encourage developers to create ARM64 apps for Snapdragon-based PCs. Microsoft’s Surface Pro X laptops run on a custom Microsoft® SQ1™ processor, developed in partnership with Qualcomm. The goal was to maximize performance, productivity, connectivity, and battery life with a revolutionary, ultra-thin design. On these devices, Microsoft used a translator to run x86 64-bit apps on arm devices.
