Updating Windows is a technical procedure, but you can always do it yourself by following the appropriate instructions. But the problem occurs when the update process gets stuck every time you try to do it. To do this, you need to change the way you update your Windows 10 system. The update you’re trying to install for Windows 10 may contain errors; so using an external source to install it may be the best solution to your problem.

Specifically, if you get the 0xc1900201 update error, you should follow the following guide. Usually, the error occurs when there is a problem with the server connection or update. However, we have prepared a list of the best solutions that can either give you a viable alternative or help you fix the error. Just follow the following steps as they can be very helpful.


What is the cause of Windows update error 0xc1900201?

What is the cause of Windows update error 0xc1900201?

We have investigated this particular issue by going through various user reviews and trying different repair strategies recommended by other concerned users who have been able to fix the problem. It turns out that several different scenarios could be triggering this particular error code. Here is a shortlist of possible culprits that may be responsible for error 0xc1900201:

Windows Update Blocked Between Updates: Under certain circumstances, this particular error code can occur because a faulty Windows update is blocked pending. In some cases, this problem may cause the entire WU component to stop and prevent the user from keeping the operating system version up to date. In this case, you can solve the problem by running the Windows Update diagnostic program to automatically detect and resolve the problem.

Faulty WU component: If the user cannot install new updates (not just one), it is likely that one or more WU components have failed and interrupted the update process. If this scenario applies, you may be able to resolve the problem by resetting all WU components (either with an automatic agent or manually with an extended CMD prompt).

The operating system already cloned: This problem very often occurs in situations where the user has previously migrated their operating system from a hard drive to a new SDD format. The mismatch is the result of a failed verification attempt due to a hardware change. In this case, you can solve the problem by using the registry editor to change the PortableOperatingSystem value.

Damaged system files: In rare cases, this problem is related to corrupted system files, which eventually affects component updates. In this case, the problem can be solved either by running some built-in utilities that can repair corrupted components (DISM and SFC) or by updating each Windows component (via a recovery installation or a clean installation).

If you are also experiencing error 0xc1900201 and one of the above scenarios applies to you, see the next section on how to solve the problem. Below is a set of possible solutions that other users have successfully used in a similar situation to get to the bottom of the problem.

If you want to be as efficient as possible, follow the instructions below in the order in which we have classified them (they are classified by efficiency and severity). Finally, you should find a solution that should solve the problem, regardless of the cause.

How to fix update error 0xc1900201 in Windows 10?

Expand the system partition

End users shouldn’t have to worry about this, but for you, it’s Windows 10. If it works, that’s fine; if not, you’ll have to resort to complicated workarounds to get it to work. In this scenario, you’ll need to resize your system partition to get the latest Falls Creator Update.

Chances are, the nominal values are around 100 MB, while it will take between 200 and 600 to get to the latest iteration of Windows 10. This is quite a complicated process, and many savvy users recommend using some sort of third-party partition management tool. The best and easiest to use is EaseUS Partition Manager.

What’s more, backing up your system before each step will cost you nothing.

  1. First, create a system repair disk in case something goes wrong.
  2. Download.
  3. Install this clever tool and get it working.
  4. Select a system partition. The one where Windows 10 is originally installed (in most cases it’s C:).
  5. Click on “resize/move”.
  6. Under “Determine size and location”, reduce the available space by about 600 MB.
  7. You will then be able to see the free and unallocated space so that you can reboot your computer.
  8. After the reboot, press the Windows + R keys to open the extended Run command line.
  9. At the command prompt, type diskmgmt.msc and press Enter.
  10. Right-click on the system partition and choose Unfold Volume.
  11. Add the previously created unallocated space to the reserved system partition and confirm the changes.
  12. Reboot your computer and try to update it again.

After that, you should be able to install all the major updates without any problems.

Using the multimedia creation tool

If the update process suddenly hangs on every attempt, you may need to change how the update is distributed and the installation source.

Windows Update is quite problematic, so your additional solution is to use an external source: a USB or DVD containing the installation files. You can create such media with a multimedia creation tool.

If the problem is related to the connection or distribution of the update files, this should fix the problem accordingly. Be sure to follow these steps to create installation media and update Windows 10 with it:

  1. Download the media creation tool.
  2. Run the tool and accept the license terms and conditions.
  3. Select “Update This PC” and the download process should begin.
  4. Once the files are downloaded, the Media Builder will begin the update process.
  5. This process should take up to 2 hours depending on your version of Windows 10 and your bandwidth.
Perform a clean reinstall

Finally, if neither of the previous two steps was successful, you can always use the Windows 10 installation media mentioned above and perform a clean reinstall. Once your system is fully updated, it should contain the Fall Creators Update, also known as version 1709.
