"Couldn't update to Windows 8.1 - 0xC1900101 - 0x40017"

I have downloaded the Windows 8.1 update from the store but cannot get it to install. Each time I try, I get to the point where it is "getting my devices ready", then the PC restarts to a blue screen with error message. It then tries to recover the installation, fails, then restores Windows 8. When the system boots up after this, I get a message saying:

"Couldn't update to Windows 8.1

Sorry, we couldn't complete the update to Windows 8.1. We've restored your previous version of Windows to this PC.

0xC1900101 - 0x40017"

There is n o explanation as to why the update could be completed. Any ideas how to resolve this?

    None of these have worked for me and have spent several hours trying various things IN ADDITION TO all of the above MS-Engineering notes.

    • Windows 8 Pro with Media Center
    • Dell Studio laptop  - 8gb RAM/320gb SSD about 40% free space/10gb System Partition
    • All Win8.0 updates drivers, patches installed. Says no more Updates available.
    • NO DEVICES OR HARD DRIVES OR PHONES plugged into laptop. Any other devices have been removed from Device Manager.
    • Removed all EXTRA devices in Device Manager.
    • Tried safe/clean boot -- made no difference.

    Also tried ...

    • Remove ATI video driver and Catalyst software so that it uses the MS driver. Made no difference.
    • Did wsreset at all intervals between all the various (read: hours) of steps -- made no difference.
    • Removed any extra third-party tools, mini-apps, etc. Difference? Made no difference.
    • Started in low-resolution mode: Made no difference.
    • Disabled WiFI and also removed Wifi driver relied only on Ethernet cable during install. No difference.
    • Windows Firewall service OFF and Defender OFF. Did it make a difference? No. No difference.
    • Did SFC /snannow from Admin Command Prompt -- made no difference

    PLEASE READ THESE MICROSOFT> Your ideas above DO NOT WORK.
