Hi, I went to Microsoft Download Center, (searched for each KB download), and was able to manually download 2 of them but was unable to download KB2533523. I've been working on this most of the day, I might have typed the wrong numbers on the one I couldn't download, I'll try that one again tomorrow. For some reason Windows Auto Update won't install them. After I installed them and verified they were installed they still came up on the Windows Auto Update, I just right clicked on them and Hid Them, (Vista), tht way they won't come up on Update as needing to be installed. (I Hid IE 9 like that too, but I didn't install it because it's not compatiable with my Email. And IE 9 kept trying to make me download it.
