It runs fine, but slow because of low VM specs, but try with convertconfig.ini set options and autorstart =1.
I built it just fine a few days ago, got 29641.1000.260729-1515.rs_flight_server_x64fre_ru-ru.iso It was with AutoStart=1, I'll check with AutoStart=0 edit: no issues with the AutoStart=0, I'm on 28000.2704 host OS this is with the 29641.1000_amd64_ru-ru_multi_62eb4764 UUP set
No, he doesn't want to. What is most interesting is that the script processes all the builds that were before this release, and this 29641 is in failure. Now I'll try to run it on WinPE and on a virtual machine.
Autostrat=0 also works: I accidentally removed the previous gif with the autostart=1 test but the picture shows it working
Strange things are happening. On my laptop on build 26300, the script refuses to work. It works on a desktop computer on 26300. I reinstalled it on my laptop to 28000 and everything went fine. Thank you for your time.

Hi abbodi, some findings in W10UI and uup-converter-wimlib that could help for improvements: W10UI: - ResetBase=2 is not applied to WinPE images, i.e. when updating ADK winpe or more usually boot.wim (:cuboot vs :cuinstall sections) - DismRoot option, as specified by user, is not applied for all dism command instances. It defaults to dism.exe in path (host OS if no ADK installed) for those instances "hardcoded" as dism.exe /english command or dism.exe command instead of using %_dism2%:"!_cabdir!" command as well. uup-converter-wimlib: - in convert-UUP.cmd, StartVirtual=1 is not supported if AutoStart=3 (install.wim only) because create_virtual_editions.cmd does not support .\install.wim only. Currently to workaround this I move the created .\install.wim to a "dummy" folder structure like ".\myiso\sources" and manually start create_virtual_editions.cmd. It throws a "file not found" error during the "=== Checking distribution Info . . ." stage, but script continues through "=== Creating Virtual Editions . . ." stage without errors.
@Reducer - Cleaning after baseline LCU in WiinPE breaks installation for the 2nd LCU - Some commands doesn't require newer dism.exe, it's compatible with Win7 or later specially some check/grab commands (for loop) will not work with full or long ADK dism.exe path - StartVirtual is ignored indeed if the target is not ISO (1 or 2) i don't know what do you need exactly?
Sorry the delay in replying, abbodi. 1. ResetBase=2 for WinPE images. The following script log shows that it is possible to resetbase after each CU for a WinPE image. Is a very basic update script, of course, just straight commands. The point is: in current W10UI some processing happens between CU apply command and the resetbase command which seems to be different depending on the target image (WinPE or not). The breaking cause could be in one of the steps of this different processing. I mean: it seems to me that :rebase section cannot simply be called from :cuboot like it is done from :cuinstall because before the final resetbase command each type of image is processed differently.

Honor DismRoot as specified by user. Your concern on exceeding max command lenght totally makes sense. However note: in current W10UI, if ADK is detected, you add its dism.exe to the script "Path" definition, which drastically cuts "_dism2" command lenght. Surprisingly, you never add "DismRoot" to "Path" for the same benefit. To confirm this I performed the following test: Spoiler: W10UI test: setup Code: 1. Default dism ADK bin path is C:\Program Files (x86)\Windows Kits\10\Assessment and Deployment Kit\Deployment Tools\amd64\DISM\dism.exe 2. "DismRoot" is set to exactly the same char lenght C:\10u\ddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddddd\dism.exe 3. "DismRoot is added to script "Path" definition at a suitable point 4. "_dism2" definition in :proceed does not use "DismRoot", but simply "dism.exe" 5. All instances of hardcoded dism.exe /English and dism.exe commands are replaced with %_dism2%:"!_cabdir!" 6. All script options are set using the menu to test behavior after changes. Note: Current W10UI rejects ADK winpe.wim as a valid target ("Detected wim version is not Windows NT 10.0"). I have to target the mounted image.

It would be nice if that kind of use case would be supported without creating unwanted additional files/folders. From UUP files to install.wim (only) with virtual editions, automated. EDIT: forgot to attach edited W10UI EDIT2: changed point where "DismRoot" is added to script "Path". Otherwise DismRoot is not used for dism commands before or during the menu.
@abbodi1406 A new PSF-specific processing tool, MSUpdateExtractor, has just been released. It has all the features of PSFExtractor and can also handle combined update files of msu, cab, wim, and psf. You can get the source code and download it at https://github.com/win-story/MSUpdateExtractor. I tried it out and replaced PSFExtractor in uup-converter-wimlib, and did all sorts of update integrations like usual. It worked really well, even a bit better than PSFExtractor. Hopefully, it can replace PSFExtractor used in the current tools.
PSFExtractor.exe is currently used only for 22000/22621 updates 22631 and later uses psfx.txt (powershell/.NET) to expand wim+psf files extracting cabs (SSU for example) may require dpx.dll from the target build DesktopDeplyment.cab depending on host os version 25398 introduced PA31 delta format, which require UpdateCompression.dll (can be renamed to msdelta.dll) to support recent 2026+ updates DesktopDeployment.cab include dpx.dll which now also have msdelta functions too
I know the principle. But I mean, all the features of PSFExtractor are supported in MSUpdateExtractor. When you use PSFExtractor, you need to carry its configuration file along with the exe, but with MSUpdateExtractor, you don’t need an extra configuration file.
I recently started to see printmanagement modern uwp app on startmenu is there an entry we can add to "CustomAppsList" to remove it?

(for both install.wim and boot.wim) 1. install the latest SSU only 2. place both LCUs in the same folder (just two or more LCU files, nothing else) 3. integrate and reinstall only the latest LCU Spoiler: manual test Code: C:\Users\usr>dism /Mount-Wim /wimfile:F:\\upds\boot.wim /index:1 /mountdir:F:\\33\mnt /English Deployment Image Servicing and Management tool Version: 10.0.28000.2804 Mounting image [==========================100.0%==========================] The operation completed successfully.

(for both install.wim and boot.wim)
When multiple checkpoint updates were tested, there was a version of uup-converter that only add the highest LCU msu, and dism would find and stage the other LCUs in the same folder by itself but i remember that did not work well with NetFx3 later
but this time it's not possible to integrate 1742 LCU with the latest SSU, I have logs somewhere on UUP dump discord server they have changed something
