Since most user reports indicate that Windows upgrade or update operations got frozen the moment Error 0xc0000409 appeared, we can narrow down the events or issues that lead to it appearing to the following:

  • Broken or damaged Windows Update components:

Sometimes, the files your system reads or employs to execute Windows Update operations become corrupted, which means your computer will struggle to install Windows updates. If our assumption about Error 0xc0000409 being triggered by file corruption events holds true, then you should be able to get things in order by resetting Windows Update components.

  • Buggy or bad Windows Insider code is blocking some processes:

If you are on the Windows Insider program and are struggling with Error 0xc0000409, then you should not be surprised to learn that the issue is somehow connected to your computer not running a stable or bug-free build of Windows 10. Well, you are hardly the only individual on the Windows Insider program who has encountered the error.

How to fix Windows 10 Error 0xc0000409

Since you now know enough about the error, it is time we moved on to describe the procedures that are commonly used to resolve it. Go through them in the order they appear below.

  1. Run the Windows Update troubleshooter:

Since the vast majority of scenarios where Error 0xc0000409 comes up has something to do with Windows Update issues manifesting themselves on devices, it is only natural that we begin with the procedure used to resolve a wide range of problems affecting Windows updates. The Windows Update troubleshooter should scan the files and components employed by Windows Update to detect faults or damage and then propose repair strategies or directly apply them on your behalf.

Follow these instructions to run the Windows Update troubleshooter on your computer:

  • Launch the Run app. This popular keyboard shortcut should assist you with the job here: Windows logo button + letter R.

Once the Run application window comes up, you must fill the text field on it with this code:

ms-settings:troubleshoot

Hit the Enter button on your PC’s keyboard to get your system to run the code.

  • Assuming the Troubleshoot screen in the Settings program is now up on your screen, you have to click on Windows Update (an item on the list under the Get up and running section).
  • Once Windows Update gets highlighted, you have to click on Run the troubleshooter button (that recently appeared under it).

Now, the Windows Update troubleshooter window should appear. You have to wait while it scans your computer.

If the troubleshooter ends up identifying an issue, you will see Apply this fix, which you have to click on.

If the troubleshooter proposes multiple repair strategies, you will do well to apply all of them.

  • Once you are done following the troubleshooter’s recommendations and applying the necessary fixes, you must close all programs and reboot your computer.
  • Check if Error 0xc0000409 has been resolved. Reattempt the operation that failed earlier.
  1. Reset Windows Update components manually:

If the Windows Update troubleshooter failed to do enough to get rid of Error 0xc0000409, then you have to take matters into your hands and perform repairs on your own. Here, we will guide you through the operations used to reset Windows Update components or restart Windows Update processes. By resetting or restarting Windows Update services, you get to force through changes that resolve the glitch or aberration defined by the error in view.

Many users actually confirmed that they were finally able to complete the Windows Update installation tasks after they applied the reset procedure for Windows Update components on their computers. You too should benefit from the same operation. Go through this guide quickly:

  • First, you have to launch an elevated Command Prompt window. You can use the Windows key + letter X keyboard shortcut to bring up the options and utilities that make up the Power User menu and then select Command Prompt (Admin).

If a User Account Control prompt shows up, you must click on the Yes button to affirm the launch operation you initiated.

  • Assuming the elevated Command Prompt window has now appeared, you must execute these lines of code one after the other:
  • net stop wuauserv
  • net stop cryptSvc
  • net stop bits
  • net stop msiserver

By the time you finish running those codes, the Windows Update Service, MSI Installer, Cryptographic Service, and BITS will have been stopped.

  • You must now move on to rename the SoftwareDistribution and Catroot2 folders. Here are the lines of code you have to execute here:
  • ren C:\Windows\SoftwareDistribution SoftwareDistribution.old
  • ren C:\Windows\System32\catroot2 Catroot2.old
  • Here, you must restart or relaunch the services we asked you to stop earlier. These are the lines of code you need to run:
  • net start wuauserv
  • net start cryptSvc
  • net start bits
  • net start msiserver
  • Close the elevated Command Prompt application and other programs. Restart your computer.
  • After Windows boots up and your system settles down, you must try to install Windows updates again or reperform the Windows upgrade task.
  1. Perform a repair install of Windows 10:

A repair install allows you to refresh the Windows operating system code on your computer without loss of files or data. Furthermore, your computer will end up with the latest Windows updates. Well, this event is an important outcome since you need to circumvent Error 0xc0000409 – if you are unable to install Windows updates currently. The repair install procedure will fix the damaged system files and install the needed Windows updates.

The operation is relatively straightforward and easy to execute – if you have all that is needed (the prerequisites and requirements). You must have at least 9GB of free space on your computer’s hard disk. You need the installation media ready for use, and it must contain the build of Windows that corresponds to the iteration you already have installed. For example, if you have 32-bit Windows 10 installed on your machine, then you must load a 32-bit Windows 10 package on the installation media.

This guide summarizes everything you need to know and provides outlines of the critical steps in the repair install process:

  • Fire up your web browser and head to Microsoft’s site. There, you must check for the Media Creation Tool and download it. Save it somewhere and then run it.

If a User Account Control prompt appears for any reason, you have to click on the Yes button to continue.

Note: You can also use an alternative utility like Rufus to do the job – if you know your way around this program. However, you will have to download the Windows ISO on your own and perform other tasks the same way.

  • You have to click on the box for the Create installation media for another PC parameter and then click on the Next button to continue.
  • Now, assuming you are on the panel for language, architecture, and edition, you must tick the box for the Use the recommended options for this PC.

Your choice here is quite critical because it ensures that the correct parameters get used throughout the Windows installation process.

  • Choose the correct language, edition, and architecture.

While the utility might allow you to embed both 32-bit and 64-bit Windows 10 installation packages on the same USB, we advise that you choose only the one you need.

  • At this point, you should be able to fill the field for the product key with the required digits – if you have a product key.

Well, if you do not provide a product key, then the utility will force you to proceed with only Home and Pro as possible edition choices for the installation. In that case, you must not forget to choose the precise version or build of Windows that was initially installed on your PC.

  • Click on the Next button.

Here, the utility is supposed to offer you two destination options for the installation of Windows 10.

  • You have to choose the USB flash drive option to proceed with things.
  • At this point, you have to insert the USB flash drive you intend to use for the purposes ahead and then click on Refresh drive list.
  • Once the inserted USB appears, you must click on it to get it highlighted and then click on Next.

The utility should now swing into action. It will begin by fetching the Windows 10 installation package, and then it will place the necessary files on the USB drive.

When everything gets done, you will know about it.

  • You can click on the Finish button.
  • Here, before you begin the actual repair install process, we advise that you disable any third-party antivirus or protection utility you have on your computer. You are better off uninstalling such programs if you really want to avoid complications or issues along the way.
  • Go into the Windows 10 installation directory. Run the setup.exe file.

If a User Account Control prompt shows up, you have to click on the Yes button to move on. The Windows 10 Setup wizard or window should come up now.

  • Click on the box for the Upgrade this PC parameter and then click on the Next button.

The Windows is getting prepared screen should appear now. You can track the progress of the process through the percentage bar.

  • On the current screen, you should see the Download and install updates parameter, whose box you have to click on. Yes, this step is quite important.
  • Click on the Next button.

The Windows 10 Setup operations will now proceed fast. Your PC is supposed to restart during the process.

  • Now, assuming your computer has started up (after the expected reboot), you have to accept the notices and license terms.
  • Once the Ready to install page shows up, you must click on Install.

At this stage, if you did not select what version or edition of Windows 10 you intend to install earlier, you will be allowed to indicate your preference now.

  • Regardless of the edition or build of Windows 10 you intend to install, you must tick the box for the Keep personal files and apps parameter. This step too is quite critical.

The repair install tasks will now commence.

  • Once everything is done, you will get a prompt to log in or you will end up on the regular Windows boot screen.

At this point, we must say we have taken you as far as we can. All you now have to do is follow the on-screen instructions to set time zones, personalize your computer, and so on.

Anyway, your PC is now running a fresh installation copy of Windows 10 on which Error 0xc0000409 cannot be triggered. You will now be able to perform the tasks you struggled with earlier due to issues defined by the error.

  1. Disable your firewall or defense shield:

We earlier established interference from your firewall or defense shields as one of the possible causes of the issues that result in the appearance of Error 0xc0000409. Well, it is time we walked you through the resolution that applies to this hypothesis.

These instructions will guide you:

  • Launch your firewall program and enter its settings menu or configuration pane. Find the switch that allows you to turn off the firewall or disable it completely. Use the turn-off or disable switch.

If your antivirus employs a firewall to protect your computer from threats, then you must go into its settings and turn it off.

If you cannot find a switch that allows you to turn off or disable your firewall or antivirus, then you should stop them from working through other means. You can try to turn off their most active or useful functionalities and see how things proceed.

In general, we want you to do anything that dissolves your firewall or prevents your protection utility from setting up a firewall. If you cannot turn off the firewall directly, then you must try to weaken it or stop the program involved from applying its rules.

  • Now, once you are done performing the recommended tasks against your firewall or protection utility, you must reattempt the operation with which you encountered Error 0xc0000409 to find out the new state of things.

If the error comes up again, you must proceed to the next step. If the Error refuses to show up, then you will know that firewall was somehow involved in causing issues for you and you can still continue to the next step.

  • Here, we want you to uninstall your firewall program or the protection utility that uses a firewall on your computer.

You can uninstall an application by initiating the removal operation for it on the Apps screen in Settings, or preferably, you can perform the task on the Uninstall a program screen in Control Panel.

You will do well to uninstall all the firewall applications or protection utilities on your computer since their removal is the only thing that guarantees they are no longer involved in causing issues for you.

  • Here, assuming you are done with the uninstallation tasks, you must restart your computer.
  • Try to perform the update or upgrade task again and see if things turn out well without Error 0xc0000409 appearing.

If Error 0xc0000409 no longer disturbs you – given the action you took against your firewall or security utility – you have to consider protecting your computer through other means, especially using less disruptive methods or setups.

For one, you can get Auslogics Anti-Malware to function as your new protection utility and guard your computer against threats. Given the way this program operates to protect computers, you are unlikely to experience the same issues that forced you to get rid of your firewall app or security program earlier.

Other things you can do to resolve the issues defined by Error 0xc0000409

  1. Download and install all Windows updates:

If you encounter Error 0xc0000409 only when you try to use certain Windows features – which means its appearance is down to a simple bug in Windows code – you are likely to stop seeing it after you get your computer to run and install all the available Windows updates.

  1. Run scans using the SFC (System File Checker) and DISM (Deployment Image Servicing and Management) tools:

If you believe the strain of Error 0xc0000409 appearing on your computer is a result of corrupted system files or a damaged Windows installation – especially if the procedures we described above failed to do enough to resolve it – then the repair and restoration operation using the utilities we recommended should help you.
