We have had to make a change to default user's registry to about 15 images to save recapturing them. Office 2012 was trying to re-register itself for every user on the deployed images. This is the task I created to do this
start /wait reg load HKU\temphive c:\users\default\ntuser.dat
start /wait reg add "HKU\temphive\Software\MicroSoft\Office\14.0\Excel\Options" /v NoReReg /t REG_DWORD /d 1 /f
start /wait reg add "HKU\temphive\Software\MicroSoft\Office\14.0\Word\Options" /v NoReReg /t REG_DWORD /d 1 /f
start /wait reg unload HKU\temphive
Created my own version of this.
reg load HKU\ntuser.dat c:\users\default\ntuser.dat
reg import englishHKU.reg
reg unload HKU\ntuser.dat
Registry build up like this:
[HKEY_USERS\ntuser.dat\Software\XXXXXXXX] - paul.theelen 12 years ago
