system-specific files are located (should
be NULL for non-ARC machines)

/*++
Routine Description:
This routine deletes those subkeys of the CCS\Enum\STORAGE\Volume key that
represent volumes that were never fully installed. This eliminates stale
information about volumes that may not exist on this computer.
The motivation for this is this scenario and others like it:
On the initial install of the OS, the disk has one large partition. The user
chooses to delete this partition and create a smaller one to hold the OS.
The result of this is that textmode setup transfers volume information about
both partitions into the system hive for the running OS. GUI mode setup then
completely installs the smaller volume, but the larger volume is left partially
installed and marked with CONFIGFLAG_REINSTALL.
Next RIPREP is run to copy the OS image to a RIS server. When the image is
brought back down, say to the same machine or to a machine with the same
hard disk size, and the automatic UseWholeDisk partitioning is done, there
will be one large partition of the same size as the original large partition.
The Volume instance name will match the partially installed one, so when
mini-GUI mode setup starts, it will get a bugcheck 7B because the partially
installed volume cannot be used as the system disk.
To combat this problem, this routine deletes all partially installed volumes
from the CCS\Enum\STORAGE\Volume key.
Arguments:
SysPrepRegHandle - Handle to the system hive of the build we are patching.
ControlSetNumber - Current control set number in the hive.
Return Value:
None.
