When Windows XP launched in 2001, the concept of booting an entire operating system from a USB flash drive was practically science fiction.

When a hard drive failed in a critical embedded system, a technician would arrive not with a dusty CD wallet, but with a keychain holding the digital ghost of an operating system. The pendrive transformed XP from a supported product into an eternal, portable artifact.
