Routine Description:
Initialize a registry based on user selection for hardware types,
software options, and user preferences.
- Create a command line for GUI setup, to be used by winlogon.
- Create/munge service list entries for device drivers being installed.
- Initialize the keyboard layout.
- Initialize a core set of fonts for use with Windows.
- Store information about selected ahrdware components for use by GUI setup.
Arguments:
SifHandle - supplies handle to loaded setup information file.
TargetRegion - supplies region descriptor for region to which the system
is to be installed.
PartitionPath - supplies the NT name for the drive of windows nt.
SystemRoot - supplies nt path of the windows nt directory.
HiveRootKeys - supplies the handles to the root key of the system, software
and default hives
HiveRootPaths - supplies the paths to the root keys of the system, software

Routine Description:
This function is only called on the upgrade case.
This function replaces the original data of 'PagingFile' on
CurrentControlSet\Session Manager\Memory Management, with the default
value '?:\pagefile.sys 15 20'.
The original value will be saved on HKEY_LOCAL_MACHINE\SYSTEM\Setup\\PageFile,
and it will be restored at the end of GUI setup.
Arguments:
hKeyCCSetControl - supplies handle to SYSTEM\CurrentControlSet\Control
hKeySystemHive - supplies handle to root of the system hive
(ie, HKEY_LOCAL_MACHINE\System).
Return Value:
Status value indicating outcome of operation.
