question about servicing stack updates

I want to ask a question here
Are servicing stack updates (ssu) required for installation of a cumluative update?
This is what i want to know

 

For Offline Image Integeration yes its needed mandatory.
For Online System Install : bleepingcomputer.com/news/microsoft/windows-10-starts-bundling-servicing-stack-updates-with-cumulative-updates/

 

So if you wanna slipstream it into an iso, you would have to insert the ssu as well? Is that correct?

 

based on official info: https://forums.mydigitallife.net/threads/windows-10-hotfix-repository.57050/page-556#post-1629480

Thanks for the info, but what do you have to install first, the ssu or the cu?

 

SSU>LCU

 

Q: what do you have to install first, the ssu or the cu?
A: It depends on the version of Servicing Stack defined in the update.mum file of the update hotfix.

Case1: 19041.630 LCU, Applicable to any version of Servicing Stack.

Package_for_RollupFix~31bf3856ad364e35~amd64~~19041.630.1.6.mum

Code:

<installerAssembly name="Microsoft-Windows-ServicingStack" version="6.0.0.0"

Case2: 19041.621 SSU, Applicable to any version of Servicing Stack.

Package_for_KB4586864~31bf3856ad364e35~amd64~~19041.621.1.0.mum

Code:

<installerAssembly name="Microsoft-Windows-ServicingStack" version="6.0.0.0"

Case3: 19041.479 20H2Enablement, Applicable to version 19041.153 of Servicing Stack.

Package_for_KB4562830~31bf3856ad364e35~amd64~~10.0.1.2.mum

Code:

<installerAssembly name="Microsoft-Windows-ServicingStack" version="10.0.19041.153"

So, for case3, Servicing Stack version 19041.153 must be existent or installed before 19041.479 20H2Enablement package can be successfully installed.

 

Yeah, that will make it more clear to novices.

Whatever the dependency is, SSU goes before LCU.
