Windows 7 post-deployment automation

I have 3000 computers to image at work, many different models. boss has no problem w me adding scripts into the ghost file he made but he doesnt want any in-depth tinkering.
After imaging, windows finishes sysprep and the full shell comes up, relying on built-in pnp and the 10gb of driverpacks my boss loaded into the image.

So i have to go to each machine multiple times to restart when needed for drivers, and eventually join the domain and use the certificate based activation.

So heres my question, is there a way to automatically monitor pnp to see when its done all it can before a reboot is necessary, reboot, skip the ctrlaltdel screen and autologin...rinse and repeat until i have to do the cert activation?


I already scripted the system rename and joining the domain using autohotkey and batch (i dont know if he has ps1 scripts enabled on the image and i cant change it if it isnt, so id rather avoid powershell if possible)

Oh and ive found modifying the reg to enable/disable autologin to be very unreliable so thats out unless you know a fool proof way that works every time
