"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 agree with augie44's reply but additionally suggest you remove all non-Microsoft drivers before updating to Win 8.1.  For example, I have Asus motherboard related drivers I skipped.  I just took whatever the Win 8 full install gave me.  Also disconnect any additional peripherals, if you have any,  before the Win 8 install.  All these can be added back after updating to Win 8.1.

    Good luck.

    And you sure won't get much help from Microsoft - how many pages does this make??

    If it's a new machine I would take it all the way back to zero - like you are just plugging it

    in.  Go to your programs and see if any pre-packaged security systems are in the programs

    and thoroughly delete them.  Then try the update again.

    Microsoft "helper" sent me a clean disc for the 8.1 update - well, that was a laugh cause my

    new machine did the same thing.  I did have AVAST installed already thinking I would protect

    myself first and had to completely delete it before the update "took".

    **** running Microsoft can't figure out their own update, nor how to help anyone.  No excuse

    for this - none.  Disgusting.

    totally agree with you, it's absurd they are not resolving this problem. Ah, and I built this pc by myself, so it's clean by definition, I only ran windows update, so there is only the stuff Update downloaded automatically. I'll try to search for something hidden, but I doubt I'll find something

    Check out your drivers.  Make sure all are updated.  I scarcely remember that when on the 

    microsoft site they listed 2 drivers for each item and there was a difference of the two. Sorry

    I'm being vague, cause I don't recall right now.  Microsoft super-tech gave me a hint and said

    to go with one and not the other (think it was the 2nd choice with the smaller download).

    Hope I am not hurting anybody, rather than helping with this tidbit.

    I'm testing 

    • Run sfc /scannow
    • Check for Windows Updates
    • Open Device Manager and update the Network Driver
    • Run all updates in the Windows Store
    • Run Windows Update again
    • Run Disk Cleanup
    • Uninstall Antivirus software
    • Delete all Temp files
    • Run "Prefetch" in the command bar and select all, then delete all
    • Restart the computer
    • Run the Windows 8.1 Update again.

    This solved my issue.
