Hi, I want to disable the PCA Service. The service handles these screens: And in my FirstLogon script there are a couple of programs that make that screen popup. So I want to disable the service during Windows 7 Setup, if possible? The regkey: I allready had this ones in one of my autounattend.xml files, but I cant find it anymore, I know its possible without creating a .reg and them importing it, should be possible to do it directly from command prompt. Thanks in advance! edit: Think I found it: <settings pass="specialize"> <component name="Microsoft-Windows-Deployment" processorArchitecture="amd64" publicKeyToken="31bf3856ad364e35" language="neutral" versionScope="nonSxS" xmlns:wcm="http://schemas.microsoft.com/WMIConfig/2002/State" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"> <RunSynchronous> <RunSynchronousCommand wcm:action="add"> <Order>1</Order> <Path>cmd /c "cmdow @ /HID & reg add HKLM\SYSTEM\CurrentControlSet\Services\PcaSvc /v Start /t REG_DWORD /d 4 /f</Path> </RunSynchronousCommand> </RunSynchronous> </component>
