Moving a disk with Windows installed on it to another system has other
problems too, although they are not (in general) as serious.
Since the user doesn't have the source, many options are 'tuned by the
installation process' to the system Windows is installed on. So it
doesn't sound as surprising that it would require a reinstall when HTT
is toggled :-)
