Hi everyone, I am new here (Hello). Just start using the guide to create unattended installation disk. Anyway I have this little question. I use the GUIRunOnce option to install Hotfixes. Then when I Sysprep the machine for final rollout, I found that the batch file will run again after the machine is restart. That is any batch files definited in the GUIRunOnce section will be activated again after every Sysprep. I was wondering if there is any way of preventing that from helping please? Thanks, Edmond.
