Yes I installed KB3020369 first before KB3125574 but couldn't finish the install for KB3125574 successfully. I think it may have been because I installed Win 7 on a partition I created with Mini Tool Partition Wizard and I didn't choose the option to format the partition when installing Win 7. Just a guess. Or maybe the Catalyst drivers I installed for my machine (Phenom II X3 CPU) was buggy. Another guess. Or maybe because I let Windows Update install automatic updates - I didn't immediately set it to Never and to start up Manual - before I installed KB3020369 and KB3125574. Another guess.
So I installed Win 7 again, and this time I chose the option to format the partition, and I didn't install the Catalyst drivers, and I immediately set Windows Update to Never and to start up Manual before it could download updates. This time it worked! I was finally able to install KB3125574.
After that, I installed KB3172605, and then I set Windows Update to install automatically. So as of now, Windows has automatically installed many more updates. I think I made a mistake. From the instructions in the above link you gave, I was under the impression that Windows Update should be set to automatic after installing KB3172605. So that's what I did but I had not yet installed the Security ONLY Updates. I have Windows Updates turned off again but I'm not sure if I should still install the Security ONLY Updates now that Windows Updates has already installed many more updates including security updates that are all not found in the Security ONLY Updates list.
