I have a total of 72 instances so far of updating or failing to install KB2310138, starting as far back as 7/9/2011. There were successes and failures. They are a combination of Important and optional updates. The definitions numbers are all different.
I don't care about the optional updates, but they were put on my computer anyway, despite me not choosing them. I cannot update the latest (1 0f 2) Important updates. One was successful. I have AOL dial-up, and the automatic updates originally failed when AOL said "GOOD BYE" to me, knocking me offline. I have tried manual update for the remaining Important update. It just hangs at 0% uploaded. GRRR!
