Why is Add-WindowsCapability so slow for RSAT?
We install RSAT for our technicians by using: Get-WindowsCapability -Name RSAT* -Online | Add-WindowsCapability -Online The download/install is incredibly slow, averaging about ~15 minutes...
I downloaded and mounted the Language and Optional Features iso, and ran Add-WindowsCapability with the -LimitAccess and -Source parameters. It was slow as hell until I rebooted. I can't believe they still haven't fixed installing them over the Internet.
As of 2-25-25 still an issue.
I downloaded the extra ISO and then ran
Get-WindowsCapability -Name RSAT* -Online -Source "D:\LanguagesAndOptionalFeatures" | Add-WindowsCapability -Online -Source "D:\LanguagesAndOptionalFeatures" -ErrorAction SilentlyContinue -LimitAccess
Worked much faster this way.
