why has vista stopped automatic updates?

Revised Post - Forgot IE9 Update KB4018271.

Only the following newly released Vista x64 manual downloads from the OS link above applied to my PC - see screenshot at bottom - KB4024402, KB4018466, KB4021903, KB4019204 and KB4018271. I have AMD CPU. The others said "does not apply". I am running WU one more time to be sure.

Forgot to mention that I had to STOP the Windows Update Service before each new manual update to prevent the endless "Searching for Updates." WU found nothing more for me than the above except for some Optional Updates. It is FINISHED :-)

EDIT - For some reason I did not have Windows Update Settings set to NEVER CHECK while doing the manual updates. That is likely why I had to stop the WU Update Service each time :-(

I was offline the whole time. OUgrad

b  Should I be downloading and manually executing each post-April monthly Malicious Smart Removal Tool (MSRT)?  In other words, even though the Windows Updater is no longer providing this monthly tool, will newer releases of it do the job they are supposed to do, were Microsoft still supporting Vista SP2?

Confirmed - MSRT is still working with Vista in Windows Update if set to Install Updates Automatically (and possibly the other two Settings above Never Check). One of several friends I've helped keep Vista up-to-date with shows MSRT ran May and June in Update History after the April 11 Update FIX. June MSRT ran before getting the June 13 update release done per this Discussion Thread. Interesting, MSRT ran, but none of the other June Updates. THEY had to be installed per this Thread. Regardless, I tell my "Vista" friends to leave their PC connected to the Internet at least 3 hours continuously once a week to make sure Windows Update has time to initiate the Install Updates Automatically Setting and at least get MSRT monthly. My Vista PC is rarely online with so many others in my "collection" :-) OUgrad
