What is Windows on Arm?

Windows on Arm refers to the running of the Microsoft Windows operating system on hardware powered by processors based on Arm architecture. This journey began in 2017 when Microsoft introduced Windows 10 to Arm-based laptops and tablets. Before this, Microsoft ran Windows primarily on computers using the x86 architecture offered by Intel and AMD.

Why is Microsoft Extending into Arm-based Hardware?

So the obvious question is: why is Microsoft extending into Arm-based hardware?

The evolution of computing has consistently aimed for greater efficiency, portability, and integration. Arm architecture, known for its power efficiency and performance, has been a staple in the mobile industry for decades. Smartphones and tablets, which require high performance without compromising on battery life, extensively use ARM processors.

Recognizing these advantages, Microsoft introduced Windows on Arm to combine the robust capabilities of Windows with the efficiency and versatility of Arm-based processors.

“Arm-based chips will be powering more than 50% of Windows PCs by 2029.” -RENE HAAS, CEO, ARM

What to Expect from Windows on Arm

Here are some of the benefits:

1. Power Efficiency

One of the primary benefits of Arm processors is their low power consumption. Devices running Windows on Arm can achieve significantly longer battery life compared to their x86 counterparts. This makes them ideal for ultra-portable laptops and hybrid devices, where mobility is necessary.

2. Always Connected

Arm processors often come with built-in cellular connectivity. This means devices running Windows on Arm can maintain an always-connected state, similar to smartphones. Users can stay connected to the internet via LTE or 5G networks, enhancing productivity on the go.

3. Instant On

Another feature borrowed from mobile devices is the instant-on capability. Arm-powered Windows devices can wake up instantly from sleep, providing a seamless user experience and making them more responsive and ready for action at any moment.

4. Silent and Cool Operation

Arm processors generate less heat and, in many cases, eliminate the need for fans. This results in quieter, cooler, and more compact devices, enhancing the user experience and expanding design possibilities for manufacturers.

5. AI Integration

Upcoming Arm devices will feature dedicated Neural Processing Units (NPUs) to handle AI tasks natively, enhancing the performance and capabilities of these devices.

The challenges Microsoft is working on to improve the Windows on Arm experience.

While Windows on Arm offers numerous advantages, it still faces a few challenges. A significant issue is software compatibility. The vast majority of Windows applications are designed for x86 architecture, creating potential compatibility issues when running on Arm.

Microsoft is addressing this problem with several strategies:

1. Emulation

Windows on Arm includes an emulation layer that allows x86 applications to run on Arm processors. While this solution works for many applications, it can result in performance overhead.

2. Native Applications

Encouraging developers to create or recompile applications natively for Arm architecture. Native Arm apps can fully utilize the architecture's capabilities, providing better performance and efficiency.

3. Windows Subsystem for Linux (WSL)

With WSL, developers can run a GNU/Linux environment on Windows without the overhead of a virtual machine, providing more flexibility and options for development on Arm-based devices.

Future Prospects for Windows on Arm

The introduction of Arm-based Windows devices like the Surface Pro X and various models from manufacturers like Lenovo and HP has demonstrated the potential of this platform. While the transition has been gradual, the increasing performance of Arm processors and growing ecosystem support suggest a promising future.

As Arm processors continue to evolve, offering more power and efficiency, the distinction between traditional x86 devices and Arm devices is likely to blur. The benefits of Arm, particularly in terms of battery life and always-connected capabilities, are appealing to both consumers and enterprises.

Moreover, the industry's push towards Arm, exemplified by Apple's successful transition of its Mac lineup to Arm-based M1 chips, sets a precedent and creates a competitive landscape that could accelerate Arm adoption in the Windows ecosystem.

So there is a good chance that your next Windows laptop won’t have an x86 chip inside!
