"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?

    I have been trying to update for 3 days now and to no avail.  I have unplugged all USB devices except for the keyboard and mouse. I see posts from over a year ago of folks having the same issue.  Here we are at the end of 2014 and still having the same problems.  What are my options, Microsoft? Very discouraged!

      I have the 0xC1900101-0x20017 issue.  

    Has anybody looked at the CBS.log which matches the time of the event as reported in ReportingEvents.log?

    I'm not a computer or software tech, so can't say for sure what the answer for you would be. Taking off Avast temporarily worked for me. I'm just thinking maybe other virus protection programs could be part of the problem in general. Don't know what program you have, but I would suggest uninstalling - or at lest disabling -  your virus protection program long enough to install 8.1. I activated Windows Defender during this process. Hopefully somebody at Microsoft is monitoring this forum so they can correct this flaw in the next version. It certainly was a MAJOR pain in the rear for me. Good luck.

    Thanks but most of us here have all disabled our anti virus.  I use Defender (An MS Product!) and disabled it prior to attempt 8 or 9.  This is beyond ridiculous.  I have the 0xC1900101-0x20017 issue.  Pretty much just giving up.  MS has as well.
