There's been plenty of recent discussion about Windows 11's Recall feature and how much of it is a garbage fire. Especially a discussion around how secure the database storing all those juicy details of your banking details, sexual peccadillos etc is from prying malware. Spoiler, it's only protected through being ACL'ed to SYSTEM and so any privilege escalation (or non-security boundary *cough*) is sufficient to leak the information.
