At an event on its Redmond campus, Microsoft announced Copilot+ PCs — a new category running AI workloads on the device — along with new Surface Pro and Surface Laptop models. One headline feature was Recall, which continuously saved snapshots of the screen so users could search for things they had seen. The backlash was immediate: Recall captured sensitive material such as passwords and financial information, and security researchers found that early builds stored it in unencrypted plain text, which settled the matter. Microsoft pulled the June rollout to all users back to Windows Insiders only, then layered on mitigations — making it opt-in, requiring Windows Hello authentication, and decrypting snapshots only at the moment of use. General availability came about a year later, in 2025. It was the sharpest concrete statement of the question of how much of a user an on-device AI may watch.
