"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 reformatted my PC. Installed from scratch. Installed no software. Works with win 8.  But once I try upgrading to 8.1 proper, it fails. I tried all ways, update drivers then upgrade. I have stripped the PC to barebones with only graphics card and a normal HDD. Get this error too. Seems like I am stuck with win 8. :(

    it is frustrating. And the PC is only two years old. Works perfectly fine. Throwing it out just doesn't cut it for me.

    For me it was Avast Antivirus **!! Uninstalling it did the trick.**I don't know how is this connected to the drivers, but i got to know this when upon restart the blue "smiley screen" (which is the first screen showing any error, and disappears very fast) showed the avast .sys file name.

    I had to completely uninstall the antivirus even disabling wouldn't help. 

    For those who are still facing the issue uninstalling AV software may help.

    YES - It worked for me too, after a long time.

    I had disabled Avast (forever, not only to next restart) but it was not enough.

    Many thanks to Spacecharge

    yes. me too.

    AVAST was the culprit. 

    after uninstalling the antivirus, 8.1 updates smoothly. 

    then i reinstalled the same.

    Thanks.

    I'm having the same issue.  From looking at some of the other posts it appears it has been almost a year since we were asked to "wait a few days" for this solution.

    I purchased my computer from HP in Sept of 2013. It arrived with Windows 8 and Microsoft Office 13 already installed. Within a few weeks I was able to upgrade to Windows 8.1 with no problems at all.  

    Just recently some kind of software glitch occurred and my computer crashed. Attempts to do a "restore" failed, but HP was able to help me "recover" the original system software; everything else was lost, so basically I started with a clean machine.

    Since then, I've been trying to upgrade to 8.1 from the Store just like the othes, and I'm getting exactly the same errors.

    I haven't contacted HP yet to see if they can help, but since I have a full maintenance agreement, I intend to so. I'm not really expecting a reply to this since the last reply was in October 2013 and it is not August 2014. Just thought I'd post it anyway.

    Charles.
