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

I am having an error message every i tried to update Window 8.1

Error Message - 0xc1900101 - 0x20030018

Kindly assist with this error.

I have exactly the same error messages.  Have uninstalled all third party autostart software, uninstalled hidden devices, run 'update driver' on every device in device manager, uninstalled antivirus software, removed all non essential hardware, ran all windows app and software updates 3x,  etc..

Rerun store 8.1 upgrade about 12 times in between all these changes. I would think that if the upgrade installation is coded in such a way to create these error codes, there would also be a way to find out what caused them to be 'tripped'.  Is there something in logs somewhere that will tell me?

I tried many different "solutions" and I was getting very very frustrated until I found this post:

"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."

Good bless this guy. It solved my problem. I follow the steps and Windows 8.1 installed without any problems. FYI I have an ASUS Zenbook UX31LA. Now I only have to deal with the noisy fan, it's driving me bananas!!! (if someone knows how to fix it, please let me know).

Try blowing out the inside of your laptop with compressed air to clean your fan and vents. you fan most likely has a buildup of dust on the blade causing it to be unbalanced and have to work harder to spin , equaling a higher noise operation. If that fails, your fan is most likely old and reaching end of life/is faulty, and I would replace it.

I AGREE

Rajesh,

With all due respect, I'm scrolling through 79 pages of people just like me, all with different hardware, experiencing the same problem.  GM does a recall when they issue a bad product.  Can't you guys hook up a fix?  Spend a little, you guys have about 150 billion in cash.

I've pretty much given up. Over 100,000 views with similar problems and MS does not ever listen or care. I'll stay with win8 and forget win8.1. Not worth the frustration.
