I lost all of my data on a tablet that had Bitlocker installed without my knowledge. Not one time was I ever told that my drive was encrypted or that there was even something called Bitlocker or that I should write down some password or code. Bitlocker activated because of an OS update, and I had no way to unlock it so I had to wipe the drive. I don’t have an MS account, because I have no need to give MS all of my data, so I couldn’t unlock it that way either. And no, I’m not a 20 year old; I’m someone who has used computers since before the internet and have no interest in setting up a corporate account for every watch, shoe, phone, video game, car, etc. I have no interest in giving MS all of my pictures, documents, emails, and browsing history.
