No one seems to know much about this process. I never did figure out how to actually control LO4 during sysprep and have instead moved to calling a script from the setupcomplete.cmd to copy my settings and shortcuts into the default user upon first boot. Doing it this way also insures that every new user that logs into the machine will get the same default setup and desktop icons.
This seems to work well and achieved all of my goals however I view this as a work around and not a real solution. Ideally it would be nice to find out what is tripping the reset to defaults and how to control that process.
Basically the process is this:
configure a users profile the way you want it.
created a folder under system32 that contains the following
one folder containing the profile settings from c:\Users%username%\AppData\Roaming\LibreOffice
one folder containing the desktop shortcuts to be placed in default user
Create a new batch script with the following:
@echo off
REM OfficeSettings.bat
REM ##source =C:\Windows\System32\A_Image_Identity\Office_Settings
REM ##destination 1= C:\Users\Default\AppData\Roaming
REM ##destination 2= C:\Users\Administrator\AppData\Roaming
ECHO Setting up LibreOffice 4.0
c:\
cd C:\Windows\System32\A_Image_Identity\Office_Settings
XCOPY /e /h /y /c /i *.* C:\Users\Default\AppData\Roaming
XCOPY /e /h /y /c /i *.* C:\Users\Administrator\AppData\Roaming
cd ..
cd C:\Windows\System32\A_Image_Identity\Office_Shortcuts
XCOPY /e /h /y /c /i *.* C:\Users\Default\Desktop
XCOPY /e /h /y /c /i *.* C:\Users\Administrator\Desktop
::EOF
EXIT
Then in c:\windows\setup\scripts you will typically create something like this and call your new batch script from there.
REM SetupComplete.cmd
del /Q /F c:\windows\system32\sysprep\unattend.xml
del /Q /F c:\windows\panther\unattend.xml
REM - Starting Libre Office Setup
start C:\Windows\System32\A_Image_Identity\office_settings.bat
::EOF
exit
On a sysprepped image SetupComplete.cmd will run automatically upon first boot of the machine and will call the officesettings.bat script. This will allow you to setup all setting the way you want them and copy them to the default user. I would advise not setting the user specific info in your default setting since this will be replicated to all further users. I will be using for general settings only.
