Hello! I am doing some experiments by installing all the updates offline and I get some hiccups. In particular KB4018556 and KB4036162 will show in windows update as 23KB files (the mpsyschk.exe). Any idea why I get those instead of the actual update? Even when I use windows update to install those they just show up again. What am I suppose to do with those mpsyschk files? Also no way to install mrt KB890830 offline and windows update won't detect anything past that level unless I install mrt from windows update. Something else that I found out is that there are many updates that show up initially but they are in fact superseeded by other updates on the same list. In the catalog they are not listed as superseeded but nevertheless many won't apply either if I install first the 2020-01 Security Monthly Quality Rollup. Anyone with more knowledge on this can give some input? Thank you all!
