What is Windows on ARM?

What is Windows on ARM?Windows on ARM, often referred to as Windows ARM, is a version of the Microsoft Windows operating system designed to run on devices powered by ARM (Advanced RISC Machines) architecture. Unlike traditional Windows versions that primarily run on x86 and x64 processors, Windows ARM is optimized for ARM-based processors commonly found in mobile devices, tablets, and certain laptops.

Key features and aspects of Windows ARM include:

Processor Architecture. Windows ARM is specifically tailored to work with ARM-based processors, which are known for their energy efficiency and widespread use in mobile devices. ARM processors are designed to provide a balance between performance and power consumption.

Energy Efficiency. ARM architecture is known for its energy-efficient design, making it suitable for devices with limited power resources, such as tablets and thin-and-light laptops. Windows ARM aims to deliver a responsive and power-efficient computing experience.

Compatibility. While Windows ARM has compatibility with a wide range of Universal Windows Platform (UWP) applications available through the Microsoft Store, traditional Win32 applications designed for x86 or x64 architecture may require emulation to run on ARM-based devices.


Also Microsoft provides tools like the Windows on ARM64 compatibility layer to facilitate compatibility.

Connected Standby. Windows ARM devices often support features like Connected Standby, allowing them to remain in a low-power state while still receiving notifications and updates. This contributes to improved battery life and an always-connected experience.

LTE Connectivity. Many Windows ARM devices are equipped with LTE connectivity, enabling users to stay connected to the internet without relying solely on Wi-Fi. This feature is especially beneficial for users who need internet access while on the go.

Device Form Factors. Windows ARM is commonly found on devices with form factors such as 2-in-1 convertibles, detachable tablets, and slim laptops. These devices aim to provide a balance between portability and productivity.
