We might get 19045.4474 eventually for public release

I'll appreciate little help. I want to integrate updates to (iot) LTSC 2021 (19044.1288 3 in 1). Which minimal no. of files do I need. Are files from uupdump here: https://forums.mydigitallife.net/threads/windows-10-hotfix-repository.57050/page-739#post-1836794 enough?

 

When you use the Release Preview updates to create an uptodate ISO, these updates will be integrated:

Code:

1/5: SSU-19041.4467-x64.cab [SSU]
2/5: Windows10.0-KB5015684-x64.cab [Enablement]
3/5: windows10.0-kb5032906-x64.cab [Setup DU]
4/5: windows10.0-kb5034232-x64.cab [SafeOS DU]
5/5: Windows10.0-KB5037849-x64.cab [LCU]

This should be ok.

 

Can I merge windows 10 19045.4472 aio (made with uupdump) and LTSC 2021 19044.4472 (made with WU script) into one ISO (one install.esd) and how?

 

dism /export-image would be one way to do it.

 

Just install.esd?

 

first convert your ESD to WIM for both images
then export any index to another image, convert final WIM to ESD again if you want

winre.wim might increase the file size, so it's better to include one of them in all indexes
also, you can't compress the final image well if the builds are really different, so make sure both have been updated with the same updates set and cleanup+resetbase applied

 

How to include winre.wim into indexes? Do I have to change anything into boot.wim and winre.wim?

 

1. dism /export-image your-aio.esd/wim /all aio.wim /compress:max /checkintegrity
2. dism /export-image ltsc.esd/wim /all ltsc.wim /compress:max /checkintegrity
3. dism /export-image aio.wim /all install.wim /compress:max /checkintegrity
4. dism /export-image ltsc.wim /all install.wim /compress:max /checkintegrity
5. (optional) dism /export-image install.wim /all install.esd /compress:recovery /checkintegrity

This should be it.

you can use this small script with wimlib
it extracts winre.wim from the 1st index and then adds it to all indexes

Code:

@echo off
reg query HKU\S-1-5-19 1>nul 2>nul || (if not "%1"=="am_admin" (powershell start -verb runas '%0' am_admin & exit /b))
pushd "%~dp0"

set "_wimlib=bin64\wimlib-imagex.exe"

%_wimlib% extract install.wim 1 Windows\System32\Recovery\winre.wim --no-acls --no-attributes
echo.

for /f "tokens=3 delims=: " %%i in ('%_wimlib% info install.wim ^| findstr /c:"Image Count"') do set images=%%i
for /L %%i in (1,1,%images%) do %_wimlib% update install.wim %%i --command="add 'winre.wim' '\Windows\System32\Recovery\winre.wim'"

del winre.wim
