So, make sure you work your way down the list until you find the one that works best for you.

Method 1: Updating or Removing Corrupted Drivers

For this solution, you need to locate all faulty drivers in your computer. To do that, you can follow the steps below:

  1. On your keyboard, press Windows Key+E to launch the File Explorer.
  2. Now, navigate to this path:
  3. Scroll down until you find the Panther folder. Double-click it to open it.
  4. Identify the problematic drivers by opening the Setuperr.log and Setupact.log files. Remember that you can only open the files if you take ownership over them.
  5. Once you’ve determined the problematic drivers, uninstall them.

You can also use the Device Manager to identify faulty drivers. Simply follow the instructions below to proceed:

  1. Go to your taskbar, then right-click the Windows icon.
  2. Select Device Manager from the options.
  3. Once you’re inside the Device Manager, expand every category to see the list of devices under it. It is likely that you will see a yellow exclamation mark beside the device causing the 0xc1900101 error.
  4. You can either update or remove the problematic driver. To do any of those, you need to right-click the device, then select the option you prefer (Update Driver or Uninstall Device).

As you can see, the process of fixing problematic drivers can be complicated and time-consuming. Thankfully, there is an easier and faster way to deal with this issue. Even if you do not have sophisticated tech skills, you can use Auslogics Driver Updater to resolve all your driver-related problems. After installing this software program, it will automatically detect your operating system version and processor type. It will also scan your computer and find all the faulty drivers. All you need to do is click a button to prompt the tool to fix all your driver-related issues.
After getting rid of the 0xc1900101 error, you can try installing the update again. You should be able to upgrade your operating system without any issues.

Method 2: Disconnecting Your External Hardware Devices

There are users who reported that they were able to install the Windows 10 Creators Update after they had disconnected their external hardware devices from their PC. You may think that this a third-grade solution for such a complicated problem. However, it has been proven to be useful for many users. So, it is still worth a shot.

Method 3: Removing Your Extra RAM or Network Card

If the previous solutions did not work for you, it is only natural to ask, “What are the causes of the 0xc1900101 errors?” Well, if driver incompatibility issues are not behind the problem, then it is likely that the error has something to do with your additional RAM. As such, we suggest that you remove one RAM module. Once you’ve done that, try installing the Windows 10 Creators Update again. If the error persists, you can try removing the network card as well.

Method 4: Running an SFC Scan

One of the reasons why the c1900101 error appears is because you have system files that are damaged or corrupted. Thankfully, Windows has a built-in tool intended for fixing issues like this. You can run a scan, using the System File Checker (SFC) to resolve the problem. Here are the steps:

  1. On your keyboard, press Windows Key+S.
  2. Inside the Search box, type “cmd” (no quotes).
  3. Right-click Command Prompt from the results, then select Run as Administrator.
  4. Once Command Prompt is up, type “sfc/ scannow” (no quotes), then hit Enter.
  5. Keep in mind that the scan process usually takes a couple of minutes. Make sure you avoid interfering with it.

Once the process is complete, try upgrading your operating system again. If the error persists, we suggest that you use the Microsoft Windows Deployment Image Servicing and Management (DISM) tool as an extra measure for repairing corrupted or damaged system files. To proceed, follow the instructions below:

  1. Go to your taskbar, then click the Search icon.
  2. Type “cmd.exe” (no quotes).
  3. From the results, right-click Command Prompt, then select Run as Administrator from the context menu.
  4. Make sure you give permission to run the app.
  5. Inside Command Prompt, run the command line below:

DISM.exe /Online /Cleanup-image /Restorehealth
The process will take even longer than the SFC scan. So, just be patient and wait for it to complete.

Method 5: Checking if you Have Enough Space for the Upgrade

Keep in mind that you need to have at least 16GB worth of storage space in your computer when you want to install the Windows 10 Creators Update. If you do not meet this minimum requirement, you might encounter various 0xC1900101 errors. So, we recommend that you free up hard drive space to fix the problem and to install the update successfully.

There are various ways to regain some megabytes of storage space on your hard drive. If you are wary of losing essential files, you can use the Disk Cleanup tool to get rid of unnecessary junk files in your computer. To take advantage of this feature, you simply need to follow the instructions below:

  1. Open File Explorer by pressing Windows Key+E on your keyboard.
  2. Right-click the drive you want to clean, then select Properties from the context menu.
  3. Once the Properties window is up, click the Disk Cleanup button. The utility will begin calculating the amount of space you can regain.
  4. Select all the junk files you want to remove, then click OK.
  5. To remove unnecessary system files, click the ‘Clean up system files’ button.

You can also disable the Hibernation mode to gain more storage space on your hard drive. It is worth noting that your system saves the contents of your RAM memory on your hard drive whenever you enter the Hibernation mode.

Doing so allows your PC to save the system state without using power. Consequently, you can pick up where you left the next time you boot your computer. However, this feature can take up valuable space on your hard drive. So, we suggest that you disable it.

You should also check if there are programs on your computer that you are no longer using. Keep in mind that these applications may take a considerable amount of disk space. If you uninstall them, you will regain more megabytes on your hard drive. To get rid of unnecessary programs, you simply need to follow the steps below:

  1. Press Windows Key on your keyboard.
  2. Now, type “Control Panel” (no quotes), then hit Enter.
  3. Select Uninstall a Program under the Programs category.
  4. Look for the applications that you are no longer using.
  5. Right-click each program, then select Uninstall.

There are still other methods to free up space on your hard drive. However, the easiest way to do so is to use Auslogics BoostSpeed. This tool has a powerful cleaning module that sweeps out all kinds of PC junk. With one click of a button, you can regain valuable storage space and improve the performance of your computer.

So, it is best that you get rid of them before performing the upgrade.

Method 9: Accessing BIOS to Disable Your LAN Card

The peripheral devices connected to your PC may be behind the problem. One of the most common causes of the issue is the wireless adapter. However, there are still some cases wherein the Ethernet adapter is the actual culprit.
To resolve this issue, it is advisable to access BIOS and disable the onboard LAN feature from there. If you do not know how to get to BIOS Setup, we recommend that you check your motherboard manual. Keep in mind that the method for accessing this feature varies depending on the computer brand. So, your best option is to check your motherboard manual.

After disabling the onboard LAN feature from BIOS, try performing the upgrade again. Once you’ve installed the Windows Creators Update successfully, remember to activate the onboard LAN feature again.

Method 10: Upgrading Your BIOS

Another workaround for the 0xC1900101 error is upgrading your BIOS. Some users reported that outdated BIOS can prevent the upgrade process from running successfully. So, to get rid of the error, it would be helpful to update your BIOS. That said, you must remember that this procedure can be complicated. If done wrong, it may cause damage to your computer. As such, we encourage you to consult your motherboard manual to get the detailed instructions.
