What it detects

This rule identifies registry value deletion events where the WindowsAI\DisableAIDataAnalysis value is removed from policy keys under either HKCU or HKLM. Deleting this value indicates that the Windows Recall feature may be transitioning from disabled to enabled, which can support post-exploitation discovery and data collection. The detection relies on Windows registry delete telemetry capturing EventType=DeleteValue and TargetObject ending in the specified policy value name.
