The only things that MCE doesn't have that x64 does (since x64 is Pro only) are:
* Ability to join a domain (and this can actually be done, but it will break media extenders)
* Credman, which the component that allows you to save credentials, say if you map a drive and want it to persist across logons or reboots.
Otherwise, they are essentially identical, except for the obvious x86/x64 architectural differences and the addition of the MCE bits in the MCE SKU.
