Attempting to create a fresh copy of XP Professional OS. It is installed and working OK but I cannot get Windows updates. I've tried several MS Fixits and the one thing it has not been able to fix is the following: "Service registration is missing or corrupt". How do I fix this? This presumes that I'll be able to get updates if this is fixed. I have already checked "services.msc" to ensure that Updates is set to automatic and that BITS has started. Your help is appreciated.
