When Microsoft launched its Copilot+ AI PC initiative over the summer, one of the flagship features was Recall, a feature that would log months' worth of your PC usage, with the stated goal of helping you remember things you did and find them again. But if you've heard of Recall, it's probably because of the problems that surfaced in preview builds of Windows before the feature could launch: It stored all of its data in plaintext, and it was relatively trivial for other users on the PC (or for malicious software) to access the database and screenshots, potentially exposing huge amounts of user data. Microsoft was supposed to launch Recall over the summer but delayed the feature to rework it.
