Recall
Recall is a Windows AI feature introduced by Microsoft that achieves context awareness by continuously capturing screenshots and having AI index the user's screen content. Due to privacy and security controversies, it is set to be disabled by default.
Core Facts
Microsoft Recall is a feature released with Copilot+ PCs in 2024 that takes screenshots every few seconds and uses a local AI model to build a semantic index, allowing users to retrieve content that has appeared on their screen using natural language.
Microsoft's Recall feature, introduced in 2024, was forced to be delayed due to privacy controversy arising from its continuous screenshotting and AI-based indexing of user activity.
Security researchers discovered that Recall stored screenshots locally in an unencrypted SQLite database, sparking privacy controversy, after which Microsoft changed it to require users to actively enable it and added Windows Hello verification, encryption, and sensitive content filtering
Timeline (last 90 days)
In RAG scenarios, Recall is usually prioritized over Precision, because missing a piece of key evidence often directly leads to an incorrect answer, whereas retrieving a few extra irrelevant documents only increases context noise and token cost.
After Microsoft Recall sparked strong controversy for being enabled by default, it was changed to optional and given stronger encryption.
Microsoft Recall is a system-level feature in Windows 11 that periodically takes screenshots and builds a local index, allowing users to search past activity in natural language.
Microsoft Copilot+ PC's Recall feature adopts a continuous screenshot plus semantic indexing approach, but was forced to delay its launch due to privacy controversies.
