Running W10UI v10.62 with same Configuration no error show.
for builds 28000+, 2 and 3 has the same effect for 26100 based builds, 3 seems better 1 is the preferable and the default choice
suggestion for the new W10UI / uup-converter updates: remove LCUmsuExpand 2 at all, LCUmsuExpand 3 could be renamed to LCUmsuExpand 2 instead based on this: https://forums.mydigitallife.net/posts/1922367 currently, LCUmsuExpand 1 and LCUmsuExpand 3 should be fully sufficient
i would just make them equivalent (as they are for 28000+) or i can fix that by adding the Baseline LCU before latest SSU and skip it for reinstallation after NetFx3
Why does uup-converter-wimlib-126 ignore setting LCU to Winre.wim if LCUmsuExpand=2 and LCUmsuExpand=3 are enabled with LCUwinre =1 enabled? Please take a test.
check readme Code: LCUwinre Force updating winre.wim with Cumulative Update even if SafeOS update detected. This option is ignored and auto disabled for builds 26052 and later. it is ignored for builds 26052+ more info by msft: https://learn.microsoft.com/en-us/w...amic-update#update-windows-installation-media for winre.wim: 1. Add servicing stack update via latest cumulative update 2. Add Safe OS Dynamic Update 3. Clean up the image 4. Export image
It must be forced when LCUwinre =1 is enabled, and it is ignored when LCUmsuExpand=2 and LCUmsuExpand=3. With LCUmsuExpand=0 and LCUmsuExpand=1, everything runs smoothly.
no, it should be ignored for builds 26052+ according to readme you never mentioned what build you are trying to build anyway, so the whole conversation makes no sense so far
There is a person who wrote this script and prescribed this item, which should work when the mode is turned on on any assembly as desired. The image was created on build 26340 and is present in the original LCU image in Winre.wim.
I have a question: starting with Windows 11 Version 24H2, Virtualization-based Security (VBS) is enabled by default. Is there any way to modify install.wim to disable Virtualization-based Security (VBS) in advance?
https://forums.mydigitallife.net/threads/windows-10-hotfix-repository.57050/page-783#post-1922461 upcoming change for W10UI and builds 26100+: highest LCU msu will be added to boot.wim, regardless LCUmsuExpand value should i implement this when boot.wim already have an integrated LCU, and W10UI is used with W10MUI? or whenever boot.wim already have an integrated LCU?
