What is BitLocker — Windows disk encryption that protects data on a lost or stolen device
BitLocker is Windows' built-in disk encryption. It protects data when the PC is off or the drive is removed, turning a theft or loss into ciphertext. The big pitfall is the recovery key — lose it and you lock yourself out. It does not protect a running, logged-in PC, so pair it with a strong login and auto-lock.
BitLocker vs 'Device encryption' — the same technology, full version vs automatic lite
BitLocker and Device encryption share the same encryption engine. Device encryption = the automatic, lite version that works on Home (auto-on with a Microsoft account, recovery key auto-escrowed, minimal options). BitLocker = the full version on Pro+ (startup PIN, external-drive encryption via To Go, fine control). For individuals, being auto-encrypted plus knowing where the recovery key is is usually enough. The state matters more than the name.
