Can Microsoft’s Copilot+ PC Turn ARM Windows into an AI Powerhouse?

With Microsoft and its partners launching AI‑enabled Copilot+ PCs, developers must assess the potential of building on Windows for ARM devices.

Microsoft’s Copilot+ platform supports Windows‑based ARM hardware and is positioned as a possible “killer app” to draw developers to ARM Windows.

Some view it as a flashy stunt to generate buzz, but Microsoft has spent over a decade trying to attract developers and mainstream customers to ARM Windows.

Will developers now come?

Microsoft MVP Richard Campbell warns that without strong customer demand, converting applications to ARM will be difficult, and devices that cannot run needed apps will fail to gain users.

He suggests Copilot may be a workaround, recalling Microsoft’s earlier, less successful attempts to sell Windows on ARM, and posits that Copilot could be the key to a successful ARM product.

While more native Windows ARM apps are emerging, it remains unclear whether they are sufficient to convince developers the platform is viable.

Copilot+ and SoC

At the recent Build conference, Microsoft announced Copilot+, with PCs priced around $1,000, offered by partners such as Acer, Asus, Dell, HP, Lenovo, and Samsung.

These Windows ARM devices run on Qualcomm’s latest Snapdragon X series SoCs, delivering strong CPU performance and AI inference capabilities. The Snapdragon X Elite is an ARM64 SoC that includes a neural processing unit (NPU) capable of over 400,000 TOPS, promising a 20‑fold performance boost over traditional PCs and 100‑fold efficiency for AI workloads.

The impressive Snapdragon SoC, especially its high‑performance NPU, suggests Copilot will run well on this hardware, and the promised long battery life adds to its appeal.

Xebia’s VP of Strategy, Microsoft MVP Rockford Lhotka, expressed cautious optimism, eager to test the battery‑life claims in real‑world use.

Huge Potential

Some Microsoft developers see Copilot+ and AI use cases as a killer application for Windows on ARM, driving adoption and developer interest.

Vasil Buraliev, project manager at VBU Consulting, argues that AI could become a flagship Windows‑on‑ARM app, combining performance advantages, native optimization, and a strategic ecosystem to position Windows on ARM as a leading AI innovation platform.

He also notes Microsoft’s track record of pushing strategic initiatives to the forefront over years.

Copilot Runtime

Microsoft’s Windows Copilot Runtime brings the Copilot stack into Windows, injecting AI into every layer. The runtime includes the Windows Copilot library—an API set backed by AI models on over 40 devices—and provides AI frameworks and toolchains to help developers integrate their own models.

Microsoft also introduced Windows Semantic Index, a new OS feature that enhances search and adds capabilities such as Recall.

GPT‑6 Outlook

Microsoft AI CEO Mustafa Suleyman predicts that while GPT‑5 will be highly anticipated, true breakthroughs will arrive with GPT‑6, which he expects to follow instructions and act on intent, requiring exponentially larger training compute.

Suleyman, appointed head of Microsoft AI in March, illustrated GPT‑6’s potential with a dinner‑booking scenario, emphasizing the need for 99% API call accuracy to meet consumer standards.

He also warned about the dangers of fully autonomous AI agents, calling for regulation.

OpenAI CTO Mira Murati compared GPT‑3 to a child, GPT‑4 to a high‑school student, and said the next model will reach “doctoral‑level” intelligence, slated for release in about a year and a half.
