    Sometimes having multiple firewalls, antivirus or malware programs, may at times prevent you from performing certain tasks or running processes on your PC.

    If this is the cause of the issue, turn either of the three off temporarily and then try to log in again.

    Ensure you turn these programs back on immediately after you’re done to prevent hackers, viruses, and worms from damaging your system.

    Try to use an alternative security solution that won’t cause any errors in your system. Many Windows 10/11 compatible antiviruses are proven to be very stable and provide top-level protection.

    We recommend you use a security tool with a strong privacy policy, a powerful firewall, and a good threat database. On top of that, make sure to get an antivirus with low CPU usage.

    The background programs that start with Windows operating system could cause the Windows 10 fails c1900101-4000d error by preventing a successful installation.

    Probably one of the best-known Windows 10 cleanup software is CCleaner. This application can remove junk files, but it also has a plethora of other features.

    So running the built-in troubleshooter resolves any issues that prevent you from updating your OS.

    4. Disconnect multiple hard disks and any devices attached

    Sometimes hardware may interfere with the normal Windows boot and installation process as Windows tries to detect and install them.

    In this case, unplug all devices connected to your computers such as a printer, scanner, digital camera, USB device, CD/DVD, mp3 player, media card reader, and any other external devices you have plugged in.

    Keep only your mouse, monitor, and keyboard (if using a PC). Disconnect multiple disks installed on your computer except for the target hard disk in which you will install Windows 10 OS.

    If you have RAID configuration, disable the controller, and other devices attached as they confuse the Windows 10 setup.

    Once you do this, unplug the computer from the power outlet on the wall, remove the laptop battery, hold the power button down for 10-15 seconds, then plug back the power outlet and restart.

    5. Use Command Prompt (Admin)

    Power down your PC, and wait for about 10 minutes then start it again. The setup will automatically restore the previous Windows 10 build or previous Windows version on your PC.

    6. Remove or reduce RAM

    Sometimes, Windows 10 fails c1900101-4000d error can be caused by bad memory modules which in turn affect Windows 10 installation.

  • Hold the Windows Key + S.
  • Type Settings in the search box, and click on it.
  • Go to Accounts, and select Family and other users.
  • Click on Add someone else to this PC.
  • Fill in the form with the username and password. Your new user account will be created.
  • Click on Change account type.
  • Click the drop down arrow, and choose Administrator to set the account to administrator level.
  • Restart your PC.
  • Login to the new account you just created.
  • If the issue goes away, then it may mean your other user profile is corrupted.

  • Raise back your old account to its default admin level.
