Many many people when updating to Windows 8.1 from Store gets this error message. They first receives a notification "Getting Devices Ready", then the PC restarts to a blue screen with error message. It then tries to recover the upgrading, but fails, then restores to Windows 8. After the 2nd reboot Windows 8 recovers with 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

Someone who was stuck in that trouble found workarounds to fix it. If you get that error I would suggest you to try these steps and check if this resolves the issue.

1. If you installed any Steelseries engine software, now REMOVE it and re-try to install Windows 8.1

2. Do you have Nvidia graphics cards on your PC? Please UPDATE your NVIDIA Driver right here. Nvidia has posted the updated drivers needed for 8.1 on their website:

3. Do you install ESET Smart Security or ESET NOD32 Antivirus? Uninstall ESET, restart your PC then try upgrading to Windows 8.1. For more information you can see this ESET Knowledgebase: How do I safely upgrade to Windows 8.x with ESET Smart Security or ESET NOD32 Antivirus installed?

4. Do you install Trusteer Rapport? Please try to disable it or download the latest version and restart your computer.

5. If not try one of these below methods:

Method 1:

Remove all external devices connected to the PC except keyboard and mouse. Reboot and try to install.

Method 2:

If the issue still appears, boot the computer in a Clean Boot state and then try to install and check. Booting the computer in a clean boot state uses a minimal set of drivers and start-up programs. A clean boot helps eliminate software conflicts. Many users experiencing this issue may be able to install Windows 8.1 in Clean Boot mode.
You can refer to this article for more information:


Method 3: Update the Device Drivers on the Computer.

Step 1: Check the Windows updates for any latest driver updates.

Check in Windows updates if any driver updates are available. If so, install the same and check if it helps.

a) Press “Windows Logo” + “W” keys from the keyboard.
b) Type “Updates” in the search bar and click on “Install optional updates” from the left pane.
c) From the “Windows Update” window, click on “Check for Updates” on the top left corner, to receive a fresh list of updates and then install all the updates listed there.

For any issues while installing Windows Updates, you may also refer to this link:

Troubleshoot problems with installing updates

If no driver updates are available via Windows Update, then you may install them for all the devices on the computer from the Computer Manufacturer’s website.

Step 2: Update Driver Software from the Manufacturer’s website:

Go to the computer manufacturer’s website and search for the latest Windows 8 drivers available for all the devices on the computer and then install them by following the instructions given in the website.

Please leave your comment if you have you error fixed by any of above solution.
