"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?

    Ok, a quick update from me. Problem solved!

    I installed the most recent Nvidia driver and temporarily disabled my AVG anti-virus. Re-installed Windows 8.1 without incident second time around. I am pretty convinced in my case that the NVidia driver was the fault so if you are having difficulties

    • as others have said - this should be your first port of call. 8.1 is much improved over 8 so I am happy that I persevered with this. Good luck if you are still having issues

    I also have an Intel RST raid controller although not for my primary disk which is an SSD running on a Microsoft AHCI driver (via PCI card). The RST controls a couple of non-RAID larger conventional disks. It's a Dell which needs the special Intel drivers to install operating systems although using the PCI card got around that. It was a bit fiddly when I upgraded and did a clean install to 8. 

    The Intel drivers seem a likely candidate.

    i had the same issue on a bootcamp windows 8 install on a mac. for me, the problem was the steelseries software steelseries provided with their gaming mice. uninstalling it solved that and allowed me to upgrade with no issues. partly my lack of paying attention, but i'd double check any software that comes with devices, such as printer software and the like

    I have tried all the "fixes" that Martin and everyone else has tried on this forum and a couple of other forums but the same problem exists.

     I have three office machines and a personal laptop and have tried numerous times with all these machines to no avail. So it is not simply a "driver" or "external component" issue which with the laptop doesn't apply anyway.

    The one thing I have noticed that from the Store download page the instructions state that a Microsoft licence acceptance pop up should appear after the download and if it is NOT accepted the machine will restore the previous version of windows. That pop up has never appeared after any of my downloads, the installation begins immediately without acceptance.

    Could this be the reason for failure I wonder?

     Is this page for accepting the license agreement missing from some download server files?

     It is also not 8.1 RT I am trying to update but 8.1 Pro.

     Somebody somewhere has cocked up the download files with some parts missing or corrupt I would suggest.

    Could it be that the mighty and all powerful Microsoft corporation has fallen on it's collective face at the last hurdle, perish the thought.

    PS I am using the UK download servers.

    To keep everyone updated, a Microsoft rep got in touch to suggest it might be my Realtek High Def Audio drivers that are causing the problem. I tried updating the driver and uninstalling the driver and neither of these actions has helped. The problem remains as before.
