To import your registry settings to the PE hive you need to modify the path in the reg files. In your example you enter a temporary name for the hive, such as WinPE. Lets say I want to import the tcp registry settings to use PE Network Configurator (PENetCfg) to simplify networking functions in the PE environment. According to the support documents from http://pierre.orgfree.com/ here are the registry keys needed to enable PENetCfg in my PE environment. "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\Root\LEGACY_TCPIPREG" "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\tcpipreg" Export them to your project directory Here are the keys, and thier subsets. [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\Root\LEGACY_TCPIPREG] "NextInstance"=dword:00000001 [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\Root\LEGACY_TCPIPREG\0000] "Service"="tcpipreg" "Legacy"=dword:00000001 "ConfigFlags"=dword:00000000 "Class"="LegacyDriver" "ClassGUID"="{8ECC055D-047F-11D1-A537-0000F8753ED1}" "DeviceDesc"="TCP/IP Registry Compatibility" "Capabilities"=dword:00000000 [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Enum\Root\LEGACY_TCPIPREG\0000\Control] "ActiveService"="tcpipreg" [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\tcpipreg] "DisplayName"="TCP/IP Registry Compatibility" "ImagePath"=hex(2):53,00,79,00,73,00,74,00,65,00,6d,00,33,00,32,00,5c,00,64,00,\ 72,00,69,00,76,00,65,00,72,00,73,00,5c,00,74,00,63,00,70,00,69,00,70,00,72,\ 00,65,00,67,00,2e,00,73,00,79,00,73,00,00,00 "Description"="Provides compatibility for legacy applications which interact with TCP/IP through the registry.

The registry keys now include the path of HKLM\WinPE\SYSTEM [HKEY_LOCAL_MACHINE\WinPE\SYSTEM\CurrentControlSet\Enum\Root\LEGACY_TCPIPREG] "NextInstance"=dword:00000001 [HKEY_LOCAL_MACHINE\WinPE\SYSTEM\CurrentControlSet\Enum\Root\LEGACY_TCPIPREG\0000] "Service"="tcpipreg" "Legacy"=dword:00000001 "ConfigFlags"=dword:00000000 "Class"="LegacyDriver" "ClassGUID"="{8ECC055D-047F-11D1-A537-0000F8753ED1}" "DeviceDesc"="TCP/IP Registry Compatibility" "Capabilities"=dword:00000000 [HKEY_LOCAL_MACHINE\WinPE\SYSTEM\CurrentControlSet\Enum\Root\LEGACY_TCPIPREG\0000\Control] "ActiveService"="tcpipreg" [HKEY_LOCAL_MACHINE\WinPE\SYSTEM\CurrentControlSet\services\tcpipreg] "DisplayName"="TCP/IP Registry Compatibility" "ImagePath"=hex(2):53,00,79,00,73,00,74,00,65,00,6d,00,33,00,32,00,5c,00,64,00,\ 72,00,69,00,76,00,65,00,72,00,73,00,5c,00,74,00,63,00,70,00,69,00,70,00,72,\ 00,65,00,67,00,2e,00,73,00,79,00,73,00,00,00 "Description"="Provides compatibility for legacy applications which interact with TCP/IP through the registry.
