Erreur de mise à jour Windows 10 0xC1900200


As with many errors in Windows, 0xc1900200 the error code indicates when you try to perform system activities (in this case, a system update).

While most people have alluded to the error that appears when attempting to install Microsoft's latest "Creator Update," it is also known to appear in a number of other circumstances.

The underlying problem with this error is that it is due to the fact that Windows cannot use the "system partition" on your hard drives.

This is a reserved part of the hard drive, used by Windows to maintain the likes of updates and files of Windows products. If you find this error, it usually means that the space on this part of the hard drive is missing and needs to be expanded.

Although you can update the size of the drive in Windows itself, the best way to solve the problem is to use a custom "partition" application, which can accurately manage the different partitions of the operating system. This tutorial explains how.

The error usually appears with the following message:

Code 0xC1900200: Windows Update Encountered Unknown Error

The way to fix it is to first make sure that the "system partition" of your system is the right size, and then you will be able to fix any problems that Windows might have with the core of its system.


1. Download and run the Disk Sharing Tool

I'm not able to recommend a specific tool, but it's important to get a reliable one.

There are a number of them that are completely free; you don't have to pay for it.


For the purposes of this article, I will tell you how to use the internal Windows 10 tool "Disk Manager".

It's not as reliable as those in bull-trading, but it can help if there are problems:

  • Press the "Windows" + "S" keys on your keyboard
  • Type "Disk Management"
  • Click on the list that says "Create and format disk partitions"
  • This will bring up a list of hard drives and their partitions
  • Look at the "Reserved System" section

At this point, you need to look at the dimensions of the "available space" in the reserved system partition.

If the amount of free space is not less than 100 MB, you will need to extend it ...

  • Right-click and select "Volume Up"
  • If this is not available, you may need to "shrink" the primary partition of the hard drive
  • If available, set the size to something like 350 MB or 500 MB (depending on the size of your hard drive)

If you can't extend the drive from Windows' disk management tool, you might want to consider downloading a "just to see" trading tool if you can do it there.

If you download a tool and it doesn't even allow extended functionality, it means you need to shrink the main unit and then expand the reserved system.

2. Run the troubleshooter for Windows Update

Regardless of whether or not the above is successful, you can take advantage of another feature of Windows 10 – "Troubleshooting".

This essentially eliminates errors/issues within the system itself, allowing users to fix all the main issues that often affect Windows.

So, if you're having problems with Windows Update, you'll want to run "Update Issues":

  • Press the Windows + I keys on your keyboard (loading "Settings")
  • Select "Update & Security"
  • Select "Troubleshooting" from the left menu
  • From the list that appears, select "Windows Update"
  • Click on "Run Run Troubleshooter"
  • Let the process work
  • Restart your system once done

This usually solves most windows Update issues, but it obviously doesn't mean that your error will be resolved.

If the error persists, you should proceed to the next step.

3. Run DISM, SFC etc.

SFC (System File Controller) and Disma (Image Imaging Service and Management) are built-in applications (command lines) in Windows.

They are used to fix specific problems within the system and essentially erase most of the temporary files that the system needs to function.

À cet effet, l’étape suivante consiste à utiliser chacun de ces outils dans votre système:

  • Appuyez sur les touches « Windows » + « S » de votre clavier
  • Tapez « CMD »
  • Lorsque la liste apparaît, faites un clic droit sur « Invite de commandes » et sélectionnez « Exécuter en tant qu’administrateur »
  • Lorsque le CMD est chargé, appuyez sur ce qui suit:
  • « SFC / skannow » + appuyez sur « Entrée »
  • « DISM / Online / Cleanup-image / Restorehealth » + appuyez sur « Entrée »
  • Autoriser n’importe quel service à analyser votre système
  • Redémarrez après la fin

Cela devrait effacer tous les fichiers mis à jour frauduleux qui espionnent sur votre disque.

Une fois que vous avez fait cela, vous pouvez également supprimer tous les fichiers Windows.

4. Clean the disk

The next step is to erase all files that may be on the disk.

To do this, you can simply use Windows' "Disk Cleanup Tool":

  • Press the "Windows" + "S" keys on your keyboard
  • Search for "Disk Cleanup"
  • Select the first option that appears
  • Click "Erase System Files"
  • Allow the system to scan your system files
  • Erase all the files it detects
  • Restart your PC

Once you have done that, try your system again.

If the error persists, it means that you have a deeper problem with Windows (it is likely that the system partition is not of the appropriate size).
