Can I run Windows on a thumb drive?

Episode 1457 (2:03:52)

Richard from Spring Hill, FL
USB thumb drive

Richard wants to know if he can run Windows off a thumb drive for security. Leo says that's a smart idea and it's not uncommon for Linux users. He should just understand that it will be slower. But it will enable him to simply reboot if something goes wrong. Leo recommends using a disk imaging command to make a disk image onto his thumb drive and then he can just blast it back on when it goes wrong. He can even make it bootable.
