Does anyone have cn_windows_10_consumer_edition_version_1809_updated_sept_2018_arm64_dvd_76148eed.iso?
Update: WSUS still doesn't have the FOD, but if you have the appropriate Features On Demand ISO you can mount it then add to the above command line: "-LimitAccess -Source X:\" where X is the drive letter where the FOD is mounted. Example: Code: Get-WindowsCapability -Online | ? {$_.Name -like "*RSAT*" -and $_.State -eq "NotPresent"} | Add-WindowsCapability -Online -LimitAccess -Source X:\ It may be an illusion, but it seems to go faster if you actually have the "Settings>Apps>Manage Optional Features" open while it's running.
I downloaded and installed it by Control Panel without problems. In RS4 were problem with this procedure.
