Fortunately, it’s the usual suspects that most often cause the error. Antivirus software, anything that locks files, monitors file changes and a few other pieces of software such as Daemon tools and system drivers. Sorting out these will also get Windows 10 installed in no time.


  • Boot your computer back into normal mode.
  • Navigate to C:$Windows.~BTSourcesPanther or C:$Windows.~BTsourcesRollback. Look for a file called ‘setuperr.log’. This should tell you exactly what is causing the issue.
  • Then find out what is stopping the install, address it by uninstalling, disabling or updating and retry the installation.


Also if you’re not comfortable reading log files, we can use the broad-brush approach and address the most common issues that are causing 0xC1900101 installation errors.

  • First, uninstall your firewall, antivirus, and any malware detection software you have installed.
  • Then, uninstall anything that locks files, for example, Spybot, Adaware or any encryption software.

  • Update all of your graphics, audio, network and motherboard drivers.
  • Perform a final Windows Update before the install so you have everything up to date.
  • In the end, Retry the installation.


If still, that does not work, we can run System File Checker and Deployment Imaging and Servicing Management to verify the integrity of your existing Windows install.

  • Open a Command Prompt as an administrator.
  • Type ‘sfc /scannow’. Let the process run and correct any errors is may find.
  • Then, Type ‘dism /online /cleanup-image /restorehealth’. Again, let the process complete and correct any errors it finds.

If the process finds errors, reboot and retry the Windows 10 upgrade. But, If neither process finds anything wrong, you are going to have to perform a clean install. you have to make backups of everything you don’t want to lose. Create a System Restore Point or System Image. Perform the clean install and then use restore or the image to bring you back to a working PC again.
