Do we know if any updates install on a clean install? I know last one you had to include an old version with the new version of one update.
Of course it will but just to be sure, is it broken with the 1809 march refresh iso itself (don't update it)?
Could you show contents of these two registry? Code: [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\SideBySide\Configuration] [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Component Based Servicing]
Everyone receive this new CU (KB4490481) through Windows Update? My machine says it's up-to-date (build 17763.379)
