"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?

    Is there any chance Microsoft could acknowledge this problem? I have tried this now 7 times. Updated Nvidia drivers, Updated ALL drivers that are available on ASUS site. Updated BIOS. Tried clean boot, tried everything. But the update keeps failing and a new pc that does not have anything strang. Even disabled all the non essential devices in the BIOS. 

    Please help.

    Ah... OK.  Yeah... I'm making a backup and am going to try a refresh to start from scratch, then update - if all goes well, I'll evaluate the hassle from there.

    The thing is that I have 180 newer games installed on that PC - each one went through an install process that may or may not have modified registry settings.  If it fails catastrophically, Steam would require re-download of each one.  4Gb (rough estimate per game?) x 180 = Comcast knocking on my door.

    I think you may have misunderstood what I said.

    I restored a full sector by sector image of  Windows 8.0 made with Acronis True Image 2013 over the fresh install of the Windows 8.1 to restore my computer to the state it was in before I tried to upgrade my windows 8.0 install.  I am currently running 8.0 because I did not want to go thru the hassle of reinstalling all my apps and re-initializing my steam install. I have steam on a separate drive.

    However what you are proposing might work using the windows backup function, not sure how that would turn out, ie how you could just restore your apps and files without affecting the registry or the dll's  or some othe OS setting upgraded or installed during the upgrade process???

    Might be worth a shot but I would make certain you have a iron clad Image before attempting.

    Good luck

    Hmm... That sounds like what I might want to do.  So a W8 backup works on an 8.1 machine when restoring? This sounds like the best solution (or only one at this point).

    ctcurry... we're all in this together - I'm nvidia, but none of these solutions work for me...

    Just wanted to leave this here.

    Sadly this also failed for me.  Once my machine reboots to apply the update it immediately fails at 0% then rolls back to 8.0
