"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 read in another listing by a Microsoft support team member that there is a bug in the driver update portion of install and to give them a few days to fix it. I encountered the same error number with a dell xps15, and since I am really looking forward to this update I am hoping this si solution. hope this gives you some peace of mind

    I have the same hardware with the same result.  I have tried updating with all external peripherals disconnected, all drivers updated, Norton AntiVirus and Firewall disabled, most startup applications disabled.  No joy!

    This same error happened to me too on a custom rig I built.  This isn't making M$'s reputation look any better.  What's worse is that this error arose from a prior mishap in the Preview edition that hasn't even been fixed yet.  M$ has got some explaining to do.
