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

Hi,

the only solution to resolve the issue that you are getting is to remove the Wireless adapter, if its a laptop will be a difficult. Desktop I believe you can take it out.

Also  check for the BIOS update

Regards

FYI, I have now tried (as well as lots of other steps reported previously):

1. Removing all non-MS services from startup.
2. Disabling all on-board options but WLAN in BIOS, installed W8.1 upgrade, rebooted, ensured WLAN was also now off, rebooted, same problem.... grrr.
3. NB BIOS is latest.

Considering I have a laptop that is from indusry leader HP, with industry leader Intel hardware, and with MS as the third leg of the triumvirate, I think whatever MS has done with W8.1 is unbelievably poor.

12 days on and still nothing tangible from MS.  I'm very unimpressed.  I think what MS does not appreciate is that we use PCs as machines for work, not as an end in itself.  In other words, "it should really just work" and not require the user to go through hoops from a company that has tens of thousands of employees and yet can't get their core product working right or have the decency to make a proper public statement.  Anyone can make a mistake - we all do - but to hide behind silence is not very professional.

I give up.

Maybe someone on here can help me with my custom built PC.

I attempted to update my Windows 8.0 to 8.1.  Everything seemed ok until it got to one of the final automatic set-up screens.

At 24% it just got stuck for a whole day.  So I restarted the PC.  Now there is no way back.  It takes about an hour to get to a maintenance screen - but no safe mode button is on the screen.

I am given the option to install Windows 8 or 8.1, but neither work.

The SSD appears to be locked if I try to role back to Windows 8.  Windows 8.1 to loops back to the start after about and hour of thinking.

I get the  feeling that W 8.1 does not like the Quadro FX graphics card drivers, but I cannot get into safe mode to disable the drivers.

Basically I have bricked PC and 256GB SSD is locked.

I cannot even manage to get run a clean install from my Windows installation disk.

Any help would be appreciated.

Bill

Same issue here.  Dell XPS15, i7 Quad Core

I,ve also tried it for the 7th time to install this update with the new nvidea drivers that came out

but without result.I still think that this 0xc1900101 is because you have an oem version.

(but i could be wrong)
