Nadella pitches Windows PCs as AI-powered software builders

Microsoft CEO Satya Nadella said Copilot can let Windows PCs build needed software locally without cloud token costs, describing each machine as an infinite software factory. The company is shifting app hosting into Copilot rather than relying on app stores, but IT leaders remain concerned about citizen-built tools. Microsoft engineers noted that local inference does not make sessions fully offline, and routing is expected later in the month.

Nadella's X post followed a Windows and Surface launch. He said Copilot Code could let a desktop create whatever software is needed without cloud-token charges, freeing users from app-store inventories. Microsoft also detailed MAI-Code-1.1 Flash, a 137B-parameter coding model with a 256K context window tuned for PCs, plus GitHub Copilot offloading work to local models.

The company is shifting where apps live toward Copilot and promoting on-device agent security through Windows, Agent 365, and an MXC sandbox. Yet Microsoft engineers note local inference does not equal offline sessions, with routing expected later this month. IT leaders have expressed concern about tools built by non-specialist employees. The pitch also echoes Bill Gates's earlier factory vision.
