Windows Recall — a core Copilot+ feature that RTX Spark qualifies for — takes screenshots every five seconds of everything on screen, including passwords, credit card numbers, and private chats. PCWorld testing confirmed Recall still captures sensitive data despite Microsoft's filter. Security researcher Hagenah demonstrated the VBS enclave protections can be bypassed. Signal Messenger deployed DRM-based countermeasures specifically to block Recall from capturing encrypted conversations.
