"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?

    If you haven't already seen it somewhere else in these postings, the thing that did it for me was uninstalling AVAST. I didn't even try just disabling it, but uninstalled it. I activated Windows Defender before restarting my computer and went directly to the Windows Store for the download.  It took for **** ever and it was like torture waiting for it to finish after so many failures, but IT WORKED!!!!  I don't remember who posted this suggestion. If I can find out, I'll try to thank them personally, but I'm now on Windows 8.1 again. Hope this works for others as well.

    I have been trying to update since August 13. I had a hard drive failure and replaced the hard drive, installed all the operating system and other software given me by HP, everything else works but I can't upgrade to 8.1 this time. How long does it take them to fix a bug?

    Folks, we really must be patient on this one. This thread is not yet a year old and has reached a mere 77 pages. Give MS a chance to come up with a fix.

    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 think the best solution is for microsoft to send the people with registered versions on windows 8 the windows dry install disk with their own keycode for the cost of postage to resolve the problem since it seems to be their mistake and they can't seem to fix it otherwise
