What prevents Windows from running from a CD without help from the EWF?

[Gereon]

Within Windows XP (Embedded), what breaks when you try to run from read-
only media such as a CD? Is it just the registry that insists on being on
writable media, or are there more things?

If it is just the registry, is there a way we can relocate it to other
storage?

Gereon,

You cannot easy move registry hives (especially System and Software hives)
out of the system32\config dir on system partition (or at least I don't know
any easy way of doing that).
This is what NT boot sequence requires.

Any reason why you can't use El-Torito component? EWF protection?

As Konstantin said, your answer is to use the El-Torito feature. Then
you can boot from CD.
