Why can’t I move the Program Files directory via the unattend file? – via: The Old New Thing – Site Home – MSDN Blogs

You cannot move the C:\Program Files directory to another volume without installing Windows on that volume.
A small abstract from the explanation by Raymond Chen: The symbiotic relation between C:\Windows\WinSxS and C:\Program Files through NTFS hard links prevents you to move C:\Program Files (nor WinSxS) to a different disk volume. Both directories need to be on the same volume because of the NTFS hard link limitation.
NTFS hardlinks do save a ton of diskspace, even though WinSxS will keep growing over time, which means you need to do some careful disk volume planning, especially on SSD drives.
