How to Fix the Windows Update Error 9c59 Internet Explorer 11?

As stated before, the error code 9c59 is displayed when updating windows and it’s related to Internet Explorer updates. However, that is not always the case. It can appear if a system file is corrupted and if that ends up affecting the Windows update. Here are a few methods that will help you fix the issue:

Run DISM and SFC Scans

Deployment Image Servicing and Management (DISM) and System File Checker (SFC) are two troubleshooting tools that come with every Windows version. These tools are capable of scanning your system for any issues. They can also resolve them without much user input.

Both tools require Command Prompt and Windows PowerShell to work. So, it is much simpler to use. Running the SFC scan first and then the DISM scan is recommended. And here’s a simple method to run the DISM and SFC scans:

1. In the search bar, type CMD and click on Run as administrator.
2. In the command prompt window, type sfc /scannow and press Enter.
3. This will take some time but if the system checker detects anything, it will resolve them automatically. Once done, open the Command Prompt again by following the first step.
4. In the new Command Prompt window, type DISM /Online /Cleanup-Image /RestoreHealth and press Enter.
5. After it’s done, Reboot your PC and see if the error is resolved.

If any system file was causing the Windows update issue, this will solve it.
