Error 0xC1900101 – 0x40017 when installing Windows 8.1

Anonymous

Hello everyone,

We would like to thank all those who have helped us to collect data by sending us logs. The cause for error 0xC1900101 – 0x40017 is known to be faulty drivers, however it can be difficult to identify exactly which drivers are creating the error.

Note: Please double-check the error code before reading further. There are many variations of error 0xC1900101, each with a different location code -- the error extension, located after the dash. The information in this thread is intended only for location code 0x40017. If you are receiving a different location code, these steps are unlikely to resolve your issue.

There have been reports of a USB driver causing this error. Until a specific USB driver can be determined as a root cause, if you receive this error, we recommend you unplug all USB devices (other than your mouse and keyboard) as a troubleshooting step and try the upgrade again. If the upgrade is then successful, you can plug the devices back in and they should function normally.

We have identified a few drivers associated with the following hardware or software that could be causing this problem:

1. SteelSeries – Mouse and keyboard manufacture. The SteelSeries Engine is currently not supported on Windows 8.1. Please see their FAQ for more info and updates.

2. NVIDIA -- Video card manufacture. Check to make sure you’ve upgraded to the latest video drivers.

3. ESET - Antivirus and security-related products. Please see the ESET Knowledgebase to learn how to safely upgrade to Windows 8.1 with ESET Smart Security or ESET NOD32 Antivirus installed.

4. Trusteer Rapport -- Credit card fraud protection software. Trusteer recommends installing the latest update for Windows 8.1 compatibility.

If you have any of these programs installed, please let us know if disabling, uninstalling, or upgrading the software or drivers allowed you to install Windows 8.1 successfully.

We are sorry for any inconvenience and appreciate your help and understanding while we continue to investigate this issue.

Hello,

Microsoft is aware some customers are unable to install Windows 8.1 due to error 0xC1900101 -0x40017.

This error indicates a failure to boot Windows 8.1 occurred during the final parts of the update, causing the system to roll back to Windows 8. The most likely cause of this error is an incompatible driver or hardware defect. Unfortunately, due to the timing of this failure, there are often no logs, crash dumps or other diagnostic information available to investigate the issue easily, which makes it difficult to determine which, if any, of the drivers or system components are causing the update to fail.

We are currently working with the companies that develop these drivers to help them update their problematic drivers whenever they are identified. Some of the identified drivers have been listed in the original post, however due to the sheer number of drivers constantly being created by other companies all over the world, this is a daunting task. We understand that the inability to easily identify the incompatible driver can be incredibly frustrating and we are sorry for the inconvenience.

Make sure you’ve installed all the latest Windows Updates and latest drivers from your hardware and software manufacturers. You can also try uninstalling any unnecessary hardware or software prior to updating to Windows 8.1.

If your hardware and software manufacturers do not have updated drivers and you are experiencing this error, the best method for upgrading to Windows 8.1 is to clean install Windows 8, and then update to Windows 8.1 before allowing any additional drivers or software to install.

To do this:

Back up all of your personal documents and data to an external drive.
Disconnect your computer from the Internet.
Perform a clean install of Windows 8 using Windows 8 installation media (DVD or USB). For help performing a clean install of Windows, see How to perform a clean install of Windows.

Note: If you do not have media and Windows 8 was pre-installed on your PC, please contact your PC manufacturer for assistance. Otherwise to get help obtaining installation media, contact Microsoft Support. 4. Once you’ve reinstalled Windows 8, change your hardware settings so that you do not automatically install driver updates.

**>>**From the Start screen, type “System”, and then click on “View advanced system settings” in the search results. This will open the System Properties dialog.

**>>**Click on the Hardware tab, and then click Device Installation Settings.

**>>**When the Device Installation Settings window appears, click the “No, let me choose what to” button, and then “Never install driver software from Windows Update”. Click Save Changes to save the setting. 5. Reconnect your computer to the Internet. 6. Install Windows Updates. Restart the computer when prompted. 7. Open Windows Store and install Windows 8.1. 8. Afterwards, be sure to restore your hardware settings so that your device drivers once again install automatically. (Repeat Step 4, but restore this setting to “**Yes, do this automatically (recommended)”**and Save changes.)

wgan,

If the question about opening log files is from you:

Log files are text documents. They can be opened, etc., with Notepad.

I do have this file. It's about 4.2 MB. Is there anything in particular that I should be looking for? Notepad does not show line numbers, so I will be saving the file as some other name and opening it in a text editor that does show the line numbers.

The next time I try the update to Windows 8.1 will be over the weekend, but I don't know yet if it will be Saturday or Sunday. Whichever day, I can try it without the Logitech mouse.

Thanks for the info.

If you want to open a cbs.log the trick is to copy the whole file to one of your user folders and to click on the copied file in that location. Be warned these files can be quite massive in size.

This is ridiculous. I do not have any of the drivers listed. I have a 32 bit sony vaio currently running Windows 8 pro. I cannot install from the store or an iso. I tried to install NDVIDA drivers but they do not go with my laptop. Please give us an actual fix. All updates are installed, no ecternal devices are connected, Hardwired.

It gets stuck at about 80-84% when updating then it says "Couldn't update to Windows 8.1 - 0xC1900101 - 0x40017"

You say you don't have any of the drivers listed and yet you imply that you are using NVidia hardware. NVidia hardware and earlier versions of associated drivers are on the list of causes of this problem. You must have the most up-to-date drivers for your particular card installed or the upgrade will fail. It also may be an issue with your BIOS. If so, you need to upgrade it before you will be able to upgrade to Windows 8.1. This is a known problem with Sony Vaio hardware. You also may wish to consult the following for further information regarding this:

http://community.sony.com/t5/VAIO-Hardware-Networking/Availability-for-Windows-8-1-upgrade-for-Vaio-PC-s/m-p/204481#M13112

Also, if you want a fix, you will need to provide better details regarding your system, including specifics of the kinds of hardware your system has, which specific Sony Vaio model (there are dozens), and also whether or not you are using Norton security products or ever have had them installed on your system. That would be a great start. Programmers can't fix what they don't know is broken. Problems cannot be solved if it isn't known where exactly the problem exists.

But, be aware that if you don't have an up-to-date BIOS Microsoft cannot fix this.

if I submit my log file would you be able to help on that?

I had a look at that update log (or what ever the real file name is), I didn't have any clue where went wrong, I looked up the keyword 0x40017, didn't have any clue, and to that CBS.log you mentioned, I dont even know how to open it.
