Scott, thanks for your efforts. I can live without autoplay it's just annoying when something just stops working and you can't find the soloution.

Alan, I think you are referring to the two different key names that perform the same function:
NoDriveTypeAutoRun
NoDriveAutoRun

This article from TechNet describes them both and they seem to perform the same function and are definitely in the same path at either HKLM or HKCU:

I see that both keys were covered in the previous discussion, which should help others with a similar problem. Glad that you got it resolved.
