Whoever at MS decided that encrypting drives behind Windows 11 Home users' backs and not disclosing that, and also whoever at MS decided that confusing OneDrive sync with anything approaching a valid backup should lose their data and then step on a well-placed LEGO in the middle of the night

Highly irresponsible and their confusion-enabling has caused permanent data loss for people who didn't know they had a key they needed BEFORE losing access to their MS account
