RunOnceEx & Sysprep

[valter]

I have I believe a small problem. I've made Unattended Windows Installation CD and everything works just fine. All files called from RunOnceEx.cmd are installed, but the problem appears once I run Sysprep. For some reason RunOnceEx.cmd is again imported into Registry. So I've made a small script to delete whole key HKLM\Software\Microsoft\Windows\CurentVersion\RunOnceEx, but after sysprep ir sun (MiniSetup mode) RunOnceEx is imported into Registry again. I was looking for cmdlines.txt that calls RunOnceEx.cmd, but cmdlines.txt is not to be found on the system. Can anyone please help me solve this issue? Thanks in advance
