Does anyone know about the latest Windows 11, version 25H2 (26200.7899) amd64 version? Could it be that my server doesn't have this update file? Running the script to build gives the prompt 'Unable to retrieve data from Windows Update servers. Reason: EMPTY_FILELIST If this problem persists, most likely the set you are attempting to download was removed from Windows Update servers.'
Please y'all, read at least some posts back, e. g. https://forums.mydigitallife.net/th...11-uups-with-ease.75052/page-301#post-1905917. The 25H2 26200.7899 version has been pulled by MS, you can still take the 24H2 set + Enablement Package to achieve the same result.
Does anyone know about the latest Windows 11, version 25H2 (26200.7921) amd64 version Retail ? At the end of the process, I have only 26100.1.240331-1435.GE_RELEASE_CLIENTPRO_OEMRET_X64FRE_FR-FR.ISO instead of the wanted ISO. Sorry for my poor english. I don't undestand why there is this issue. Let me know please !
Did you select "Include updates" in UUPDump? Also note that only Windows 10, version 2004 or newer, can create the ISO correctly, older Windows and other platforms cannot integrate the updates and thus will spit out only the base (26100.1) ISO.
@Carlos Detweiller Yes, I select "include updates" in UUPDump. I try to create latest Windows 11, version 25H2 (26200.7921) on my current machine (Windows 25H2 26200.7840) Without sucess !!!
Is there any fix for this: ==== ERROR ==== Windows PowerShell is not detected or not working correctly. It is required for this script to work. Press 9 or q to exit. OS 29531
Then this wasn't the best place to ask Always use the latest release of W10UI, as mentioned above W10UI v59, it is working fine.
