It should work fine if you copy the installation folder on USB drive and have admin privileges on other computers as long as you prefer portable apps and hate installation :)
But please be aware the activation is locked to one computer and not the USB or software location. This means it will not be activated on other systems when you run it.
Not activated software is able to recover the full Windows Product Key even from unbootable drive just in case you need Windows re-installation. All other keys and passwords are shown partially.
