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?

At least try uninstalling whatever security system and then do the update, followed by re-installing
the security system - after so many tries it can't hurt.
What Microsoft Techs should be aware of is to at least ask if Avast is on the computer and then
proceed. Shameful that Microsoft does not acknowledge at least this problem.
Hello to everyone on this post. After experiencing this error and scrolling through dozens of pages I finally found page 75 with members reporting success after removing Avast . Thank you to all. It worked after removing Avast Internet security. Perhaps Avast need a big hint that they need to do something about their product.
I noticed quite a bit of Microsoft bashing in this post it goes to show that you shouldn't jump to conclusions before it has been worked on.
Sorry, I disagree with you. Myself and many others do not use Avast and have not been able to upgrade to 8.1. This has been going on for many months without any meaningful support or recognition of the problem from Microsoft. I could go on about this but I'll simply say they deserve the criticism that has been voiced on this forum.
And I wouldn't be so quick to say Avast is to blame, they didn't develop the 8.1 upgrade. I see it as Microsoft's responsibility to test their software and so state in their release notes a problem installing with other popular products. This they have not done to date that I know of. They won't even acknowledge that an installation problem exists.
The real problem is not Avast.

I did all the things you said and still had the error code - after uninstalling Avast security (or probably any security system) THEN it worked.
Here is what I did to fix my issue
First back up your data as always
do a full restore
after the restoring is finished install ALL the windows update make sure you check the control panel as well as the metro control panel for your updates.
Also use whatever program that comes with your computer to update your system drivers( toshiba uses service station)
Also disconnect all your peripherals except the mouse and keyboard
Then download the upgrade from the windows store and it should install.
