"Couldn't update to Windows 8.1 - 0xC1900101 - 0x40017"

I too have the same and other problems with installing Windows 8.1.

My first attempt brought about the BSOD with the comment Page_fault_in_nonpaged_area, or similar.

Went through a complete diagnosis for the computer which located a faulty USB card, now removed. Updated all drivers either by visiting manufacturers site or using a driver search and repair tool from Ashampoo. Used Cclean to clear out junk, did another diagnosis check everything came up green and tried yet again to install 8.1, the same error message occurs. This is my sixth attempt at upgrading and am now regretting ever having upgraded from Vista but I must admit to liking Windows 8. I attempted contacting the Microsoft Support Service who were confident my computer could be upgraded using their Premium Service, wrong, the ****-up is of Microsoft's making so why should I have to pay them to have it rectified? Needless to say I have tried all the other supposed 'Fixes' without success.

Thanks! The beta driver worked for me too. I think I have to retweak my display settings, but Win 8.1 installed with the beta driver like a charm. I find it pretty snappy too - the gestures finally work properly with the Logitech T650 touch pad.

My specs:

HP  h8-1420t

i7-3770 CPU @ 3.40GHz, 4 Core(s), 8 Logical Processor(s)

10 GB RAM

AMD Radeon HD 7670

For the last week I have been having the same problems as have been listed here and tried just about all the suggestions mentioned in the various posts. Out of frustration I lugged my desktop ( a bits and pieces machine)  up to the room where my modem/router is and connected it by Ethernet cable and disabled the wireless connectors, I also connected my old cabled mouse and keyboard and disconnected my wireless mouse/keyboard. HEY PRESTO the update worked after nearly 20 attempts using the wireless connection it work first time with the wired connection. The strange thing is all the wireless connections worked 100% after the update finished ( It does take a long time) without having to update any drivers and a Dell printer which had always refused to work with Windows 8 installed perfectly in Windows 8.1 just by plugging in the USB connector. I hope this experience might be of help to someone but why the install wouldn't work over a wireless connection when all the drivers were correct puzzles me.

Thanks for the heads up - which wasn't the first time I have read about this approach.

I'm glad it worked for you - unfortunately, it made no difference to me.  I disabled the wireless adapter and booted, updated and rebooted with a live LAN connection to no avail.  Same error.

MS, this problem seems to have been around for months, as identified in posts concerning the preview version.  I ask what has been asked before - what is the point of trialling software if you do not rectify the problems that are reported ahead of the release version?

To conclude my Windows 8.1 installation problems, I asked the tech how he was able to install Windows 8 fresh successfully.  Apparently in my failed attempt, it installed the ESD hidden folder on my root.  So, in order to install Windows 8 fresh (assuming the download won't install), you can run it by going to \ESD\Sources and run setup.exe from inside that folder.  I know this won't excite everyone, but if you've been through the insane ridiculous I have, there's the permanent fix (this deletes everything btw).  After that,  I installed the 65(?) updates, ran Windows 8.1 install, and here we are with a successful 8.1 machine.

So is spent another couple of hours taking out my nvidia card and any other unnecessary cards and rerunning the upgrade.

Perhaps unsurprisingly nothing changed and I still get the same error.

Come on Microsoft ... Time for a proper fix !
