- Recently downloaded Windows 10 2004 ISO and imported the wim file (did not capture, imported plain wim) to sccm console.
- Duplicated the Windows 10 1809 task sequence which is working fine and replaced the Windows 10 1809 Wim with 2004 WIM file.
Now, with the new task sequence with Windows 10 2004 image, image fails randomly fails while downloading applications (not the business application though, that is getting installed clean). Mostly it fails while installing MBAM Agent (application model)
or sometimes while running OS customization step (package model).
Our current Windows 10 1809 image still going fine without issues.
