By DISM or by W10UI_9.5? DISM failed here: https://forums.mydigitallife.net/threads/windows-10-hotfix-repository.57050/page-597#post-1646690
I am talking about manual dism usage, the msu is not handled correctly: Code: Microsoft Windows [Version 10.0.19042.844] (c) 2020 Microsoft Corporation. All rights reserved.

The DISM log file can be found at C:\Windows\Logs\DISM\dism.log C:\Windows\system32> Tools will probably first extract the combined cab and split them in two usable cabs (or apply it by using the update.mum), like W10UI_9.5 does.
MSFT being the culprit for naming the combined ssu "ssu-19041.841-x64.cab" looks like "KB4598481" which actually is the jan. 21. 2021 released ssu version.
You cannot either perform dism cleanup, then integrate kb4562830 or integrate kb4562830 and install the image in Audit mode + run dism cleanup + sysprep + capture new install.wim UUP do not have combined CU (not yet anyway)
Then it probably would work, considering the old 19041.504 SSU or higher is required for the LCU to be able to integrate/install. Will test it asap
Since CR-edge on EP-20H2 (KB4562830) will cause pending state, it is not possible to perform cleanup unless doing it in audit mode and then capturing it as a new image. The easiest way is to add all updates that don't cause a pending state first (eg SSU, Flash/Flash Eraser, NF 48, LCU) > Perform cleanup > Add all updates which will cause a pending state (eg NF 3.5, EP-20H2) > Next, If you add/enable NF 3.5 feature, you need to re-add NF 4.8 and LCU. So when you check for updates, WU will no longer offer to download and reinstall NF 4.8 and LCU.
I installed the 841 SSU and 844 LCU separatedly and was able to roll-back from 844 to 804. The 841 SSU remained installed. Since SSUs are generally uninstallable, will we be able to roll-back LCUs if they are enmeshed with SSUs?
LCU KB4601382 and SSU KB5000911 are still normal independent updates they can be installed together or separately, or uninstalled separately they just packed them together into unified cab, mainly for WSUS deployment, because WU already use UUP SSUs are permanent but because they changed CBS name to Package_for_ServicingStack, when you install the next SSU 19041.860 (KB????), SSU 19041.841 (KB5000911) can be uninstalled
It seems unnecessary for offline use, in the end the January SSU (KB4598481) was no longer needed and became redundant after the combo update package was installed. It's more ideal to expand the combo msu to get the combo cab and then expand the combo cab to get the actual SSU and LCU packages before adding them into the install.wim as W10UI does. Yes for sure. Just use the W10UI for instant or use that package installation order, to add manually with dism or maybe in other tools like msmg toolkit, ntlite etc.
So, do we still need the latest SSU when integrating the LCU? I thought the latter already included the former.
If you manually download a LCU and run it, no, that is a 2 in 1 process now. Things are a bit more complicated if you are integrating. Integrating you can use something like 7zip to extract the CU and SSU cab files and integrate like usual.
I think some have mentioned that attempting to DISM the new 2 in 1 CU fails. I used 7Zip to pull the CU and SSU cab files out of the msu and I could integrate them separately without issue.
