Scripted install hangs at "Set Engine Run Key"
My org has been using a K2000 to deploy scripted Win7 x64 images for a few years and have recently started to notice an issue, where after the "Windows setup" screen, the deployment process will hang at "Set Engine Run Key" for anywhere from 30 minutes to a few hours, and sometimes it hangs here indefinitely. During this time, all I see on the client is a black screen with a mouse cursor.
We are running K2000 version 3.7.120251 and are doing a scripted installation using Win7 x64 media.
Since deploying to the same PC will sometimes complete and sometimes not, that leads me to discount a driver issue (if a driver were missing, then one would think the deployment would never work).
At the black screen where the system is hanging, I can press shift + f10 to open a command prompt, and I have verified that the system has network connectivity at this point. The contents of c:\windows\panther are available at this link. I'm not sure what these are used for, but I've seen others include them in their posts requesting assistance.
If I open task manager while the system is on the black screen, I can see that svchost.exe is doing something, but as to what it's doing, i'm not sure and I don't know how to figure that out:
Based on the presence of wusa.exe, I'm guessing that the system is applying Windows Updates.
Any clue as to why this behavior would start suddenly without having made changes to the scripted install, or how we can prevent Windows Updates from running at this point?
