"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?

    Nope, uninstalling the NVidia driver didn't seem to help.  After the installation failure, and it restored my previous system, it did have an older NVidia driver installed.  327.something rather than the 331.40 I started with.

    I have the same issue. I have an Acer Iconia W511, no external devices connected. During first try I haven't realized that it said "Windows 8.1 Preview" in the store. Half an hour later starting the install on another computer it said "Windows 8.1 Update". Right now after updating some drivers I started the installation again. It seems that it completely re-downloads it from the store. But can I be sure with this or do I need to clear some kind of cache to not get any preview bits anymore?

    Update: The last try didn't work as well. And I don't get a blue screen, it just turns black after preapring devices and applying settings, I let it run the whole night yesterday but nothing happened. After turning off and on again Windows tries to repair the update, fails and turns into black screen again. After second turn off and on it reverts to the last installed version.

    I'm having the same issue. I attempted to install numerous times and decided to refresh my pc and went back to factory setting to see if it would work and I still get the error during "getting devices ready". I'm running home built pc - i5 sandy bridge, asus motherboard, gtx 760, Samsung ssd, etc. I'm also using a razer ultimate keyboard and razer mamba mouse.
