No sign of the servicing stack updates.
_Important When installing the servicing stack update (SSU) KB4456655 and the latest cumulative update (LCU) (KB4457128) from the Microsoft Update Catalog, install the SSU first to mitigate potential issues while installing the LCU.
From Susan Bradley -
If you install via MU/WU - the SSU is installed first behind the scenes. It’s not listed in the windows history, I had to do a dism list to see it.
On WSUS/SCCM if you approve security/critical, these SSUs have that same setting and gets installed as well.
If you install manually from the catalog - you need to watch this.
If you do not install first, you could end up with a non bootable machine.
BigFix usually publishes these Service Stack Updates, but is there ever any relevance set up to require them to install first before other updates?
