"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?

    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.

    I use a Spyder Elite from www.datacolor.com. But there are other products around. By calibrating your monitor, you're making sure displayed colors are as faithful as possible. Then you need to use the right color profiles for your printer and the paper you're using. You can find info on sites dedicated to photography. Google "Color profile management" or "icc profiles".

    Uninstalling Avast Internet Security 2014 before updating to Windows 8.1 solved the "Couldn't update to Windows 8.1 - 0xC1900101 - 0x40017" error on my laptop.

    Good luck!
