During my unattended install of Vista x64, i apply a bunch of tweaks that are run on the last step of RunOnceEx key.
These tweaks do not apply for some reason, but if i go manually and double click the .reg file then they're all added and i can see the changes.
During the unattended install i apply teaks twice using C:\Windows\Regedit.exe and C:\Windows\SysWOW64\Regedit.exe . It still doesn't work.
Has anyone encountered this issue before?
Any ideas are appreciated.

check unattended setup log for executions/errors.
you can find log file inside "Windows\Panther\UnattendGC\setupact.log"

see what happened with ur registry command. post log here too ( just OOBE or sysprep phase log wherever u have given command to run ur tweak ).

Hi,

there are no errors relating to registry in the log file.

This is how i call the tweaks in the batch file:

REGEDIT /S \\myserver\myshare\Apps\Registry\Tweaks64.reg
%windir%\syswow64\regedit.exe /S \\myserver\myshare\Apps\Registry\Tweaks64.reg

The network drive is obviously mapped since all the other apps install, except registry tweaks.

Test the tweak in normal mode. i.e. without silent switch.
This will check whether your batch file runs that .reg file or not.
