Recall is a feature of Windows 11 that takes a screenshot of a user's desktop every few seconds and then uses on-device large language models to allow a user to retrieve items and information that had previously been on their screen. It was announced by Microsoft, alongside the integration of GPT-4o into Copilot and an upgraded user interface in Windows 11.[1] Recall's release immediately caused controversy, with experts warning that the feature could be a "disaster" for security and privacy,[2] particularly since there was initially no option for users to disable it.[3] This backlash prompted Microsoft to postpone its rollout.[2][4] Microsoft changed the feature to opt-in and provided instructions for how to remove it.[5]
Backlash against Recall was centered on both security and privacy. Upon its release, Recall was described as a "potential security nightmare".[6] The initial version of Recall saved all data to a plaintext database, making it easy for the data to be stolen.[7] Later versions of Recall have added encryption.[3]
