If you are a Windows user, you already know very well how important Windows updates are. They solve system bugs, get rid of errors, speed up lots of system processes and, in general, are a great way to optimize your PC. In most cases, Windows updates are installed automatically with no errors getting in the way.

However, some Windows users have recently encountered the 9C59 error code whenever they attempted to install a particular update or when trying to update Internet Explorer.

If you have also run into this error code recently, you are in the right place. In today’s post, we will tell you how to resolve the Internet Explorer Error 9c59 when updating.

What Is the Windows Update Error 9C59?

The 9C59 error code can occur for several reasons. We’ve narrowed this down to the most common causes of the problem and here they are:

Corrupted Windows Update Components

This one of the most common reasons behind this particular error code. In fact, a corrupted Windows component can cause quite a few issues on your computer. Luckily, this can be easily fixed by simply running SFC and DISM scans.

Update Restrictions

If you are having trouble updating your Internet Explorer, this may be related to an update restriction. In this case, the problem can be fixed by using an offline installer to set up the browser instead.

Kaspersky Conflicts

Out of all popular anti-virus programs, Kaspersky seems to be the most common culprit when it comes to causing conflict with Internet Explorer updates. Did you run into the error code while using Kaspersky as your default anti-malware solution? You should be able to get rid of this problem by simply switching to a different anti-virus and clean installing the browser again.

TCP or IP Roadblocks

Yet another reason you may be having trouble with updates on Windows is corrupted temp data. In this case, you will need to uninstall the older version of Internet Explorer and then create a .bat file for removing the files remaining from a previous installation.

System File Corruption

In some situations, you may be seeing this error code as a direct consequence of an underlying system file corruption. It messes with your operating system’s ability to install new pending updates. If this happens, you will need to refresh every Windows component by performing a clean install or a repair install.

Naturally, as there can be quite a few causes for the error code, there are also several possible solutions.

How to Fix the Windows Update Error Code 9c59?

Below, we will go over a list of potential fixes for the 9C59 error code. Hopefully, you won’t need to go through all of them. What we suggest is that you start at the top (we will list the quickest and simplest fixes at the beginning), If the first solution doesn’t work, simply move on to the next one. Here are the solutions we will try:

  • Running SFC and DISM scans
  • Installing Internet Explorer 11 using an offline installer
  • Solving a conflict with Kaspersky
  • Removing the most common roadblocks
  • And performing a clean install or a repair install

Fix One: Run SFC and DISM scans

Are running into the 9C59 error code with every new update you are trying to install? If so, start by trying a couple of built-in Windows utilities that have been designed to deal with system file corruptions.

Try running System File Checker and Deployment Image Servicing and Management scans. They will help you identify corrupted files that may be causing the error and quickly replace them with healthy alternatives.

Note that while an SFC scan and a DISM scan share a lot of similarities, they also go about fixing corruptions differently.

An SFC scan employs a locally stored archive to replace corrupted items with healthy equivalents. A DISM scan, on the other hand, uses a sub-component of Windows Update to download new clean files.

We suggest you start by running an SFC scan first. Here’s how to do it:

  • On your keyboard, press Win + X keys at the same time.
  • This will take you to the main menu.
  • Click Command Prompt (Admin) to launch the Command Prompt as an administrator.
  • When the program opens, enter “sfc /scannow” (no quotes) and press Enter.
  • The scan and repair process will not begin. Keep Command Prompt open until the scan completes.
  • Once the SFC scan is finished, restart your PC.

When your PC boots back up, run a DISM scan. Here’s how to do it:

  • On your keyboard, press the Win + X key combo.
  • You will find yourself in the main menu.
  • Here, select Command Prompt.
    Right-click it and choose Run as Administrator.
  • Type “DISM /Online /Cleanup-Image /RestoreHealth” (no quotes).
  • Press Enter to execute the command.
  • Wait for the scan to complete — it can take from five to twenty minutes.
  • Sometimes, the progress may deem to stop at 20% — this is nothing to worry about. You will just need to wait a bit more.
  • Once the scan completes, restart your computer.

If this doesn’t work, move on to the next fix.

Fix Two: Install Internet Explorer 11 With an Offline Installer

If you are running into the 9C59 error code when trying to install or update Internet Explorer 11, there is a quick fix you can try. All you need to do is install Internet Explorer 11 using an offline installer. Here’s how to proceed:

  • Open your default browser.
  • Go to the download page for Internet Explorer 11.
  • Once you are there, scroll down to the list of download items and click the hyperlink that matches your Windows version and language.
  • When the download is complete, double-click the file.
  • Click Yes to in the UAC (User Account Control) prompt.
  • Next, follow the on-screen instructions to complete the installation of Internet Explorer 11.
  • If everything goes well and the 9C59 error code didn’t get in the way, simply restart your PC and then launch the browser.

Fix Three: Solve the Kaspersky Conflict

Are you using Kaspersky as your active anti-malware solution while trying to perform an update? If so, there is a high chance that a network agent component in the app is getting in the way.

Several users who have encountered the same problem have managed to fix it by simply uninstalling Kaspersky. Then, they initiate a CMD command to quickly remove any remaining trace of an old Internet Explorer installation. Once this is done, you can proceed to re-install Internet Explorer 11 from scratch.

Here are the step-by-step instructions:

  • On your keyboard, press Win + R keys at the same time.
  • This will open the Run dialog box.
  • In the Run search box, type in “appwiz.cpl” (no quotes) and press the Enter key.
  • This will take you to the Programs and Features menu.
  • Once there, scroll down the list of installed applications until you find Kaspersky.
  • Right-click it.
  • In the context menu, click Uninstall.
  • On the uninstallation screen, follow the on-screen prompts.
  • Next, close the Apps & Features screen.
  • Open the Run dialog box again.
  • In the Run search bar, type “cmd” (no quotes).
  • Then, use the Ctrl + Shift + Enter key component to launch an elevated Command Prompt.
  • When prompted, click Yes to the UAC (User Account Control) agreement.
  • In the elevated Command Prompt, copy and paste the following command:
  • FORFILES /P %WINDIR%\servicing\Packages /M Microsoft-Windows-InternetExplorer-*11.*.mum /c “cmd /c echo Uninstalling package @fname && start /w pkgmgr /up:@fname /norestart”
  • Press Enter.
  • Wait for the command to execute and restart your PC.
  • When your computer boots back up, go on to install Internet Explorer 11 (via a Windows Update or by using an offline installer).
  • Note that once you have disabled Kaspersky on your computer, you will need another anti-virus solution for your system to keep your computer safe. We suggest using Auslogics Anti-Malware. The program is great at detecting even the rarest malicious items that could be lurking on your PC. You will be able to schedule automatic scans and choose between the following options:
  • Quick Scan (for checking the main folders on your PC)
  • A Deep Scan (for checking your entire system)
  • And a Custom Scan (for checking specific files and folders that you find suspicious).

The best thing about Auslogics Anti-Malware is that it has been designed specifically for Windows and will never get into conflicts with your OS updates. Plus, it can run alongside other anti-virus programs.

Fix Four: Remove the Most Common Roadblocks

Did you encounter this error code on Windows 7 PRO? There could be a shared conflict between Internet Explorer 9 and a Network folder that contains read-only data. The folder couldn’t be modified according to what is needed for Internet Explorer 11 installation.

Here’s what you can do to fix this:

  • Use the Win +R key combo to go to Run.

If you are still seeing the same error code, move on to the final solution in our list.

Fix Five: Perform a Clean Install or a Repair Install

If none of the above solutions have worked, you may be dealing with a system corruption that is severely affecting your ability to update Windows.

If this is the case, the only thing you can do to fix the problem is to perform repair install or a clean install.

Keep in mind that if you decide to go with a repair install (in-place repair), you’ll need to have your installation media ready. This is a good option for when you have sensitive information on your C drive that you want to keep.

Alternatively, if you are looking for a quicker way to refresh every Windows component, a clean install is the way to go. In this case, compatible installation media won’t be required and you will be able to start the process directly from the GUI (Graphic User Interface) menu in Windows.

There you have it. We hope that the solutions above have helped you get rid of the 9C59 error code. Which of these fixes has worked the best for you? Please share in the comments below.
