Windows Recall is an AI feature for Windows 11 that continuously takes screenshots of everything on a user's screen and stores them locally, so the user can later search their own history by typing questions like "find that recipe I was looking at last week." Announced in May 2024, it faced immediate criticism from security and privacy experts and was delayed multiple times before a limited release.

Announced at Microsoft Build on May 14, 2024 as a flagship feature for Copilot+ PCs (devices with a dedicated neural processing unit capable of 40 TOPS or more). Recall uses on-device optical character recognition (OCR) and machine learning to index the content of screenshots, enabling semantic search of past activity. Upon announcement, security researchers discovered the initial version stored all data in an unencrypted database, creating a significant vulnerability. Privacy advocates described it as a keylogger-like feature, and the UK Information Commissioner's Office (ICO) opened formal discussions with Microsoft. Microsoft delayed the release multiple times, eventually making it opt-in, encrypting the database, requiring Windows Hello biometric authentication to access stored data, and allowing users to uninstall the feature entirely. As of early 2025, Recall remained in Windows Insider preview and was not yet broadly available.
