After making an iso with nlite v1.4.8 I get that annoying driver signing warnings even for drivers that are installed automatically at first boot and later for all drivers installed by me, signed and unsigned. I didn't added any drivers to my iso, just used some tweaks, few components removal and I added some KB updates to MSDN VL XP Pro N SP3 iso. I also noticed that nlite adds following lines to HIVEDEF.inf and HIVESFT.inf HKCU,"SOFTWARE\Policies\Microsoft\Windows NT\Driver Signing","BehaviorOnFailedVerify",0x00010001,0 HKLM,"SOFTWARE\Microsoft\Driver Signing","Policy",0x00000001,0 and when i go to control panel -> System -> Hardware -> Driver Signing it's really set to Ignore but with no effect at all I also used DriverSigning.exe from http://www.boot-land.net/forums/?showtopic=3095&st=60 and still no luck. Please anyone can help??
