      I am using W10 1809 x64, and defer quality updates for 25 days. However, after the time had passed (and more) I never was offered 4512577 or 4512578. I went and manually installed 4512577 with no problems 2 days ago. So I downloaded 4512578, but when I ran it it said it checked for updates then said it was not applicable to my computer. I downloaded and double-checked again to make sure it was the correct version. Same result. In between I made sure the latest SSU was installed. Any ideas as to why it would think it wasn’t applicable? I did manually install 4522015  a couple weeks ago as well as 4524148 last week, both without any problems. Could they have included everything in 4512578? I didn’t think so, but am I wrong? If not, any other ideas?

      Win10 updates are CUMULATIVE. That means that todays’ update contains yesterday’s update and tomorrow’s update contains today’s and yesterday’s.

      4512578 was issued on 9/10
      4522015 was issued 9/20 thus contained 4512578
      4512577 was issued on 9/24, thus contained 4512578 and 4522015
      4524148 was issued on 10/3 thus contained 4512578,  4522015, and 4512577

      So, if you tried to insstall an earlier one than was already installed, you were basically trying to install it a second time. Ane the computer wouldn’t let you.
      You only need the latest one.

      Ok. I know that they generally are cumulative, but as these two I mentioned installing were considered “special” patches I thought they did not contain everything previous. Thanks!
