Microsoft is again nagging Windows 10 users about upgrading to a Copilot+ PC – but this time with an Arm twist (www.techradar.com)

Microsoft is again pushing Windows 10 users toward newer Copilot+ PCs, this time highlighting progress on Arm-powered Windows devices. In a February 2025 blog post it says native Arm builds now account for apps that represent 90% of total user minutes on Windows 10 and 11 machines — meaning most everyday workloads no longer rely on x86-to-Arm translation (Microsoft’s Prism layer), which historically caused performance and efficiency penalties. Microsoft pairs this messaging with a Windows Update link encouraging trade-in/recycling as users face Windows 10 end-of-support on Oct. 14, 2025. For the AI/ML community and developers the message is significant: Arm on Windows is maturing into a first-class platform with better performance and battery life for native binaries, so targeting ARM64 can improve user experience. Key caveats remain: legacy and niche apps can still falter, and gaming is a notable weak spot because many titles rely on anti-cheat systems that blocked Arm compatibility. Epic is starting to add Easy Anti-Cheat support for Fortnite on Arm, a sign that game compatibility may improve if other devs follow. The broader implications touch developer priorities (build native Arm support), hardware refresh cycles, and environmental concerns over large-scale device replacement.
