I just can't get these older workstations to take the update. I have blown out the SoftwareDistribution folder, deleted CBS, completely reset WUAUCLT on the workstation. However, since I have been rolling out some new workstations lately, I have found that the new workstations WILL take the 20H2 update without issue from WSUS. I am continually getting this error when trying to update existing 1909 workstations (many of which had been successfully updated from 1903 to 1909 via WSUS) to 2004 or 20H2.Įrror code 0XC190010a, MOSETUP_E_UNKNOWN_CMD_LINE I have been banging my head against a wall on this one for some time.
