I added this to my "regtweaks.reg" file and it successfully enabled automatic updates for me: [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\WindowsUpdate\Auto Update] "ConfigVer"=dword:00000001 "AUOptions"=dword:00000004 "ScheduledInstallDay"=dword:00000000 "ScheduledInstallTime"=dword:00000002 [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\WindowsUpdate\Reporting] "BatchFlushAge"=dword:00000e2e "SamplingValue"=dword:000000f1 "SequenceNumber"=dword:00000002 Updates will be done automatically everyday at 2am with these registry settings.

I have the exact problem as you of Automatic updates not being enabled dispite having the correct settings in winnt.sif. I have given up and I am currently trying to figure out how to enable the setting via a registry "tweak". It appears that the area in the registry where you enable/disable automatic updates has changed with SP2.
