"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?

                CANNOT understand is the windows msg, "an error has occurred"

    That's by design so people who don't want details don't get them.  You can get details if you want them.

    I can understand computer glitches. No problem. What I CANNOT understand is the windows msg, "an error has occurred" but not explain the error so it can be fixed. Unforgivable.

    Does it make any sense at all that a huge company like Microsoft has an update for their

    OWN product and yet leaves it up to consumers to figure out how to get it to work??

    Microsoft is everywhere - much like Apple.  An update should take what is in the original

    and tweak it - not make consumers CRAZY ANGRY!!  So frustrating. 

    I'm very concerned if they do another update to 8.1 - which they surely will - what then?

    Why is not anyone from Microsoft giving any of us answers??
