Fix error 0xC1900101 on Windows 11 (and 10)

When you receive an error that begins with “0xC1900101,” it’s typically a device driver-related problem, but it can be caused by a number of other factors. For example, it could be that the system does not have enough storage space, or it could also be an issue with security software, connected peripherals, system file corruption, and more.

Regardless of the problem, you can use these troubleshooting steps to resolve the “0xC1900101” errors on Windows 11 and 10. 

Resolve storage space problems

A lot of the issues with the 0xC1900101 error can be related to storage problems.

Free up space

Windows 11 requires a minimum of 20GB of available space to process an update. If you’re trying to update or upgrade the system, if not enough space is available, you’re likely to encounter issues.

In the case of Windows 10, an upgrade requires at least 16GB of free space to install the 32-bit version of Windows 10 or 20GB for a 64-bit version.

From Windows 11

To confirm if your device has enough space, use these steps:

1. Open Settings on Windows 11.

2. Click on System.

3. Click the Storage page.

4. Confirm the free space on the main hard drive.

5. If the available space is less than 20GB, click the “Clean recommendations” setting.

   

6. Choose the files to delete.

7. Click the Clean up button.

   

On Windows 11, you have multiple ways to check storage usage on your computer. I also recommend checking these instructions to free up space on your computer.

From Windows 10

To confirm if your computer has enough space on Windows 10, use these steps:

1. Open Settings on Windows 10.

2. Click on System.

3. Click the Storage page.

4. Confirm the free space on the main hard drive.

   

5. If the available space is less than 20GB, click the “Temporary files” setting.

6. Choose the files to delete.

7. Click the Remove files button.

   

On Windows 10, you also have different ways to check storage usage. I also recommend checking these instructions to free up space on this version of the operating system.

Drive issues

You may also see an 0xC1900101 error if the setup has missing or corrupt system files. The Deployment Image Servicing and Management (DISM) and System File Checker (SFC) command-line tools can quickly resolve this issue on Windows 11 (and 10).

If the system drive contains errors, you may be unable to upgrade to a new version of the operating system. The Check Disk (chkdsk) command-line tool can troubleshoot and fix the issue. (In my experience, you have to run both the DISM, SFC, and ChkDsk commands, as shown in the steps below.)

To repair the installation of Windows 11 with the DISM and SFC command tools, use these steps:

1. Open Start.

2. Search for Command Prompt, right-click the top result, and select the Run as administrator option.

3. Type the following command and press Enter:

   dism /Online /Cleanup-image /Restorehealth

   

4. Type the following command to repair the installation and press Enter:

   SFC /scannow

   

5. Type the following command and press Enter:

   chkdsk/f c:

   

6. Type “Y” and press Enter to schedule a scan.

7. Restart the computer.

Once you complete the steps, the DISM command will repair the files inside the system’s local image, and the SFC command will use the repaired local image to fix the Windows setup files. The repair logs will be located in the C:\Windows\Logs\CBS folder inside the “CBS.log.”

Finally, the ChkDsk command will try to repair the logical and physical errors on the drive.

Alternatively, you can update the device driver by downloading and installing the latest package from your manufacturer’s support website.

Remove unnecessary peripherals

Sometimes, installation problems can be caused by a peripheral that isn’t compatible with a new version of Windows. To quickly avoid any issues, disconnect all unnecessary peripherals connected to your computer, like printers, webcams, and storage media (for example, USB flash drives and external hard drives). You only need to use the essentials, such as a network adapter to connect to the internet, monitor, keyboard, and mouse.

Also, it’s a good idea to disable Bluetooth on your computer before upgrading from Settings > Devices > Bluetooth & other devices.

Uninstall security software

Security software could also be the reason your computer fails to install an upgrade with an 0xC1900101 error. If you have an antivirus (other than the Microsoft Defender Antivirus) or other security software, make sure to disable or temporarily uninstall it before proceeding with the installation.

The steps to uninstall applications will be slightly different, depending on whether the computer is running Windows 11 or 10.

From Windows 11
