    Windows 10

    My install downloaded all of the files from the internet just fine, then it rebooted and started the actual upgrade. Got to 91% and the installation just hung for 10 hours.

    I phoned microsoft, they told me to power down the PC and reboot.


    What now?

    As for the latest Cumulative Update (KB3189866), I had the same problem on one of the 8 machines I work on at home. I downloaded the manual installer from the MS Download Catalog instead, and that worked fine. Find it here: Search results for "KB3189866" Grab the x64 or x86 (32-bit) version as your current install dictates [Note the 32-bit version is not labeled as such, it's the third entry in the list with a size of 255.4 MB.]. Hopefully, this will work for you as it did for me.
