    I just did mine right before I logged on here...lol.

    While doing so I kept getting this

    Cumulative Update KB4511555 .NET Framework 3.5, 4.8 Windows 10 Aug. 30-error.png

    After a few searches and a restart it finally corrected itself and downloaded said update. It lasted about 15 minutes. I can only guess that the server was overwhelmed with downloads.
