I'm trying to upgrade from windows 8.1 to windows 10 on my Dell XPS I keep getting error c1900101-30018 It just hangs on 32% (main) + 6% (sub) Apparently this is when it is installing drivers.

Is there anywhere on my PC I can find a log and see what driver it is failing on. I've also disconnected all my usb devices etc... before trying the update as some people where suggesting that on google searches for this error.

I've also tried upgrading a number of times and still same error. I'm using windows update to do this (not the ISO, as I don't have a flash drive / cd drive handy).


Windows 10 Upgrade Error c1900101 30018

  • Disable (preferably uninstall) your Antivirus utility before attempting the upgrade.
  • Restart a few times and try again.
  • Disable General USB Devices (example - Smart Card Reader).
  • If you are using a SCSI hard disk, make sure you have drivers available for your storage device on a thumdrive and it is connected. During Windows 10 setup, click the Custom Advanced Option and use the Load Driver command to load the appropriate driver for the SCSI drive. If this does not work and setup still fails, consider switching to a IDE based hard disk.
  • Do a clean boot and try again.
  • If you are upgrading using the .ISO file, disconnect from the Internet during setup, if you are connected by LAN (Ethernet) or Wi-Fi, disable both and attempt setup again.
  • If you are updating through Windows Update, when the download reaches 100% disconnect from the Internet LAN (Ethernet) or Wi-Fi and proceed with the installation.
  • If that does not work, try using the .ISO file to upgrade if possible.
  • If you are connected to a domain, switch to a local account
  • If you have any external devices attached to the machine, disconnect them (example, gaming controllers, USB keys, external hard disk, printers, non-essential devices).

  • I'm going to try the flash drive ISO update tomorrow when I get into the office. – DermFrench Sep 20 '15 at 21:41
  • @DermFrench Did you mange to resolve your issue? – DavidPostill Sep 23 '15 at 15:31

I assume you are upgrading through your 'reserved' free copy or by selecting "upgrade now" on the Windows 10 Media Creation Tool.

I too when upgrading one of my computers got an error like that and what solved it was the following:

  1. Download the Media Creation Tool, if you haven't already
  2. Run the Tool & Select "Create installation media for another PC" NOT Upgrade this PC now
  3. Select language, edition, and architecture that applies to you
  4. Select "USB Flash Drive", click next and choose your drive
  5. Once the setup finishes, go to your computer and open the flash drive you choose and run "setup.exe".

  • So what is stopping you from editing your answer so its relevant to the current revision of the question? – Ramhound Sep 20 '15 at 22:54
  • If you didn't notice he edited his post then I didn't either. So what's stopping me? Time, at the moment. – Insane Sep 20 '15 at 22:58
  • So don't complain about the downvote. I can't do anything about the vote until the answer is edited. I almost don't want to do anything because of your attitude over a single downvote. – Ramhound Sep 20 '15 at 23:08
