secrets are at stake, a knowledgeable thief could swipe your laptop,
nab your flash drive, or even steal the hard drive out of your

desktop PC.

routines, for example, or starting up from a different hard drive—

BitLocker presents a steel-reinforced password screen. No
password, no decryption.

In Windows 10, you also get BitLocker to Go—a disk-encryption

feature for removable drives like USB flash drives. Even if you
