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.

When I did the download and install using that, I didn't add the -LimitAccess switch.  Installed at an acceptable  pace for me.  You would thiink it would of been the other way around.

Used one of these lines, don't remember which.
