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

I have exactly the same problem:

Toshiba U400-15B  laptop.  4 GB Ram Intel Core 2 Duo P7350 @ 2.0ghz, 150GB free

Running Win 8 Pro quite happily and successfully ran Win 8.1 preview without problems.

Hard drive formatted and WIn 8 installed from disk. Only other install  Office 365.

Nothing else installed, no external keyboard / mouse or drives.

Get message after  Windows 8.1 update from the store 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"

No antivirus or firewalls installed and all updates from  Microsoft and Toshiba installed.

Help please.

Did similar as I also suspected the ATI drivers were the cause. Removing them was a bit of a job, resorted to doing in safe mode in the end as the screens kept blanking out and the whole system stopped responding when they did.

Tried an upgrade without the ATI drivers and it still failed.

As my machine has on-board graphics too I used that output for my next attempt, it behaved differently, getting stuck on 81% of "preparing devices" (or words to that effect) instead of re-booting to blank screens. Still no joy though.

Having read the installer log, the device referenced closest to the error message is my RAID controller. I think that's the next target for some investigation...

Hi,

I also have this issue.

On the Blue Screen, the error message is "SYSTEM_SERVICE_EXCEPTION - win32k.sys"

And then I have exactly the same error code: 0xC1900101 - 0x40017

-I unplugged every devices on my laptop (including the mouse)

-All my drivers are updated

My computer: laptop ASUS N71Vg

Windows 8 Professionnal (downloaded via MSDN, RTM version) - x64 / Dual boot with Ubuntu 13

Samsung Chronos series 7 laptop. Install of 8.1 seemed to go ok until reboot. Then got stuck in a reboot loop and finally got f10 to respond during one cycle with option to boot from dvd. Chose hard disk and got the message that 8.1 install failed, restoring 8.0. Then booted up ok in 8.0, and everything seemed normal. Shut down overnight. On restart - boot loop started again, but this time no f key will respond. £1000 laptop now a paperweight...

Hi - one day later and not much further forward. No amount of mashing shift f8 gets me into safe mode. Seems all function keys are not functioning... Anyway boot loop is slightly changed (changing?) After Samsung logo comes the wee blue window as before, but now sometimes two spots appear as though the rotating I'm busy signal is about to start. Also sometimes - not always, the "preparing Automatic Repair" is displayed under the window, and again it varies between one, two and three spots before the blue screen with the error message that disappears before it can be read. Then back through the cycle. Have decided to leave it cycling in case there is a hope of slow advance. (Undue optimism - maybe...)

Good ole MS! This is a huge PC problem guys - pay attention!

Are there any users with this problem without Nvidia graphics?
