Upgrade from Windows 8 to Windows 10 fails

Hi!


I've successfully updated to Windows 10 on my two Surfaces, but there is some kind of issue on my desktop PC. The upgrade process from Windows 8 fails at about 71% total (Installing features and drivers at 91%), and the error I get is:


C1900101-40017 Windows Update ran into a problem.


It's not a very helpful message, to say the least. When I click on "Get help with this error" I'm directed to a page with some general troubleshooting with Windows Update. I've run Windows update repair tool and it fixed some issues, but the installation failed again.

I have now tried freeing up more disk space which I admit was a bit tight and I'm preparing to run the update again. Still, I'd prefer if there was a more detailed error message or a log file where I could see what exactly went wrong, but there are no indications where I might find one (either in the error message, the troubleshooter, or Google). As it is, I'm shooting blind here and this will now be my fifth upgrade attempt.

If anyone has any pointers about how to proceed, any advice would be most welcome.

EDIT: Oh, and if the installation succeeds this time, I'll say so in a reply to myself and mark the thread as solved. Might save someone some trouble, hopefully.

Welcome to the windowssh blog.
We have seen lack of disk space as a problem and some have fix an install by adding space. Good luck with that.

Thanks! Sorry, too frustrated right now to properly introduce myself. :P

I hope I've freed up enough, because my SSD fills up rather quickly after I install Windows and all the developer tools I need. Can't really make a living without anything that's left after I uninstalled The Sims IV. :P

I have read that if it installs then you can reduce the space that you allocated for the install

Almost all of my 110 GB SSD drive was full after the upgrate to w10. But the culprit was not Windows: Kapsersky alone took a whopping 87 Gb, then Skype 27 Gb (never use Skype on this machine and it wasn't even installed!), then a virus called Norton (a software which infect almost every computer in the world and pass for an antivirus) also 20 Gb, and other things.

So be carefull! Delete the huge folders in question in "C:ProgramData". If you don't use the programs which have a folder in C:ProgramData, you can delete it. But do not delete folders for program which you are still using, or if they are realy excessively large, ininstall the program, delete the folder (if still necessary), then reinstall the program. Good luck.

Here's a lot of information regarding that issue. It seems to be an incompatible hardware driver, probably Graphics Card/Unit:

You seem to be correct here, but it looks like there's nothing official about it.

After I've cleaned up my disk the upgrade failed yet again, but this time the computer booted up in 1024x768 resolution, with my graphics card driver malfunctioning. Restarting the computer (Update and restart) fixed the issue, but I'm back at 8.1 again.

I guess I'll be trying out a couple of things in that thread.

Hi. I tried everything knowing it was probably a driver trying to access memory that was forbidden in Win 10. Knowing there were things starting up that weren't listed in Programs and Features of Startup I used 'Autoruns' which can be downloaded from MS or wherever. It was a revelation. It listed several drivers for long dumped printers, cards etc. I unticked a few obvious obsolete drivers and tried Win 10 upgrade again and it worked! Try it. I don't know why MS haven't offered this solution and I wonder how many users are aware of all this junk still active in the Registry?

Thank you! I'll try that too. I have no problems with Windows 10 (knock on wood) but I wouldn't mind to speed up my PC by removing startup junk. Thanks a lot! Since it is officially from Microsoft, it should be a lot safer than third-party solutions (CC Cleaner, Hijackthis and others) than can screw your PC if you don't know what you are doing.

Hi. This is just one link to Autoruns on Technet:
