Windows Update Error 0xC1900101 — Fix Driver Error During Upgrade

What Does This Error Mean?

Windows Update error 0xC1900101 means a driver is incompatible with the Windows version you are trying to install. This error most commonly appears when upgrading from Windows 10 to Windows 11, or installing a major feature update. A driver for your hardware is preventing the upgrade from completing.

Affected Models

Windows 10
Windows 11
Windows 8.1

Common Causes

An outdated driver for your graphics card, network adapter, or storage controller is incompatible with the target Windows version
A third-party antivirus or security driver is blocking the upgrade process
Your computer has hardware that is not officially supported by the version of Windows you are upgrading to
The upgrade installer cannot find or access a required driver package
Corrupted existing drivers are causing the setup process to fail

How to Fix It

Update all your drivers before attempting the upgrade. Open Device Manager, right-click each device, and choose 'Update driver.' Pay special attention to your graphics card, network adapter, and storage controller.

Most 0xC1900101 errors are solved by updating drivers before starting the Windows upgrade.
Uninstall your antivirus software before upgrading. Most major antivirus programs have a 'remove for upgrade' option, or you can uninstall from Settings > Apps.

Antivirus software has deep system hooks that often conflict with Windows upgrade installers. Reinstall it after the upgrade completes.
Disconnect all external devices. Unplug USB drives, printers, external monitors, and any other peripherals before running the upgrade.

External device drivers are a very common source of upgrade compatibility errors.
Check Windows Update for any driver updates. Go to Settings > Windows Update > Advanced options > Optional updates and install all available driver updates first.

Windows sometimes provides compatible driver updates through this channel specifically to prepare your system for upgrades.
If upgrading to Windows 11, check compatibility using the PC Health Check app. Download it from Microsoft's website and run it to see if your hardware is officially supported.

Windows 11 has strict hardware requirements including TPM 2.0. If your PC fails the check, upgrading may not be straightforward.

When to Call a Professional

If your hardware is not officially supported for the Windows version you are upgrading to, upgrading may not be possible without replacing hardware. A technician can confirm this and advise on your options, including whether a clean install might work where an upgrade fails.

Frequently Asked Questions

Which drivers most commonly cause this error?

Graphics card drivers (NVIDIA, AMD, Intel), storage controller drivers, and network adapter drivers are the most common causes. Antivirus drivers and USB controller drivers are also frequently flagged. Updating these specific drivers before upgrading resolves most cases.

Can I see which driver caused the failure?

Yes. After a failed upgrade, Windows creates a log file at C:\$WINDOWS.~BT\Sources\Panther\setupact.log Open this file in Notepad and search for 'driver' or the error code. The log will usually name the specific driver that caused the failure.

Does this error mean I cannot upgrade to Windows 11?

Not necessarily. In most cases, updating or removing the incompatible driver and retrying the upgrade works. However, if your hardware has no updated driver available for Windows 11, your upgrade options may be limited. A clean install sometimes succeeds when an in-place upgrade fails.
