Solved Windows 8.1 Update Error 0xC1900101-0x40017 on Dell XPS 18

[Palarin]

I have a Dell XPS 18 portable all-in-one machine that came with Windows 8, then I updated it to Windows 8.1 without any problems. It caught a nasty virus and I had to restore it to factory settings, which leaves me back at Windows 8.

I have tried multiple times to install the Windows 8.1 update through the Microsoft Store but keep getting Error Code 0xC1900101-0x40017. I have tried the following but get the same result;

• Ran all of Windows Updates that would come up
• Verified that all drivers were up to date. Note: my video driver is NOT a Nvidia but an Intel. I've seen posts stating that this driver needs to be updated in order to fix the problem.
• Ran Selective Start Up

I don't know what else to do at this point because I have not been able to find anything online related to my problem. Please advise if you have any suggestions. Thanks!

FYI: Antivirus running is Avast!

Hi, many people with your problem blame Avast for preventing Windows 8.1 installation - "Couldn't update to Windows 8.1 - 0xC1900101 - 0x40017" - Microsoft Community. You can try to uninstall Avast and run the Windows 8.1 upgrade.

Good luck, werty

I ended up calling Microsoft and they were able to guide me through some steps and we were able to fix the issue with the update. I wanted to post these steps in case anyone else is having the same problem.

• 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.

Once you do all of these and then run Windows 8.1 update, your screen will come to a point where you can see the User ID and the wheel spinning. I thought that the update got stuck but is was still running. This can take a little while (est. 1-3 hrs.) to complete, so be patient and once it's done, you'll have Windows 8.1 on your computer in no time.

Windows 8.1 Update Error 0xC1900101-0x40017

Tried what Microsoft requested to Palarin and it worked the very first time I tried it.

• 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 (before restart)
• 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.

The only thing I did different was I ran disk cleanup last before restart

Thank you

Many Thanks to Palarin, It worked me with the steps you mentioned.
Initially I got error when upgrading to 8.1 "0xC1900101 - 0x4000D" , I tried around 8 times since 2014 Oct. the first culprit is to uninstall antivirus if other than microsoft defender. Then I got error "0xC1900101 - 0x40017", I followed your steps it worked well.
