In the guide below, we have listed all the possible methods to fix the Windows 10 KB5018482 installation error.  

1. Run the Windows Update Troubleshooter

The first method to fix this installation error is to use the native update troubleshooter of Windows 10. This update troubleshooter scans your OS and resolves all the problems that are preventing you from updating Windows to the newest version. 

To run the Windows Update Troubleshooter, follow the steps we’ve listed below:

  1. Press Windows Key + I at the same time to open the Settings menu.
  2. Click on the “Updates & Security” option.
    Opening the Windows Updates and Security Menu
    Opening the Windows Updates and Security Menu
  3. Click on the “Troubleshoot” option from the list of options on the left side of the Window.
  4. Select “Additional troubleshooters.”

    Opening the Additional Troubleshooters menu
    Opening the Additional Troubleshooters menu
  5. Click on “Windows Update.”
  6. Select the “Run as troubleshooter” option.

    Running the Windows Update Troubleshooter
  7. Wait for a few minutes.

After a couple of minutes, the troubleshooting process will be completed, and the Windows Update Troubleshooter will inform you whether it found and resolved any problems with the OS.

After the troubleshooting process is completed, restart your PC. Once your PC has rebooted, open the Windows Updates menu and try updating to this version. If you are still unable to install this update, continue with the next solution listed below.

2. Temporarily Disable Antivirus

If you have a third-party Antivirus program installed on your PC, you should temporarily disable it before trying to install this Windows update.

While these Antivirus programs help keep our systems safe from malware, they often flag harmless processes as threats to the PC and block them from running. So if your Antivirus incorrectly flags the Windows update as a threat to your PC, it will disable it and cause errors during the installation process.

So, to ensure that your Antivirus program isn’t interfering with the Windows Update, you can disable it temporarily by following these steps:

  1. Press the Windows Key, type Windows Security in the search bar, and hit enter.
    Opening Windows Security
    Opening Windows Security
  2. Navigate to the Virus & Threat Protection category.
  3. Select the blue “Open App” button.
    Disabling Antivirus
    Temporarily Disabling Antivirus

When you click on this button, the menu of your Antivirus Program will appear on your screen. Through this menu, you can disable the Antivirus for a limited period of time

If you don’t see an option to disable the program temporarily, you can just disable the Antivirus, install the Windows Update, and then manually re-enable it. But make sure that you don’t forget to re-enable the Antivirus, as you don’t want to leave your system unprotected.

3. Perform an SFC and DISM Scan

While downloading a previous Windows update, some of your system files may have become corrupted in the process, due to factors such as an unstable internet connection, disk drive problems, power fluctuations, and so forth. These corrupted files could be the reason why the new update is unable to install on your system.

To check whether any system files are corrupted, and to fix these files, we can use the System File Checker (SFC) and Deployment Image Servicing and Management (DISM) features of Windows. These features scan your entire system for any form of corruption and quickly repairs it.

First, we will perform an SFC Scan by following the steps listed below:

  1. Press the Windows Key on your keyboard and type cmd in the search bar.
  2. Select the “Run as administrator” option.
    Opening Command Prompt as administrator
    Opening Command Prompt as administrator
  3. Type the following command in Command Prompt and press enter:
    sfc /scannow
  4. Wait for a few minutes for the SFC Scan to finish.
    Running an SFC Scan
    Running an SFC Scan

The SFC Scan will take around 10 minutes to finish. After the scan is completed, you will see a message in Command Prompt which will inform you whether the scan found and repaired any broken files in your computer. 

If you see a message saying, “Windows Resource Protection found corrupt files and successfully repaired them”, it means that the scan was successful and some corrupted system files were repaired. 

If you see the above message, restart your PC and try installing the Windows Update. If the update is successful, there is no need to perform a DISM Scan. But if you continue to encounter errors, you should subsequently perform a DISM scan as well. 

And if the message says, “Windows Protection did not find any integrity violations.”, it means that there is no problem with the system files. In this case, you should perform a DISM scan right after.

Follow the steps below to perform a DISM scan:

  1. Press Windows Key + R at the same time to open the Run Dialog Box.
  2. Type msconfig and press enter.
    Opening Services
    Opening Services
  3. Navigate to the “Services” tab.
  4. Located the “Windows Update” service and remove the checkmark next to it before pressing Apply.

  10. Restart your PC.

After restarting your PC, try installing the Windows Update. If it still displays an error, continue with the next solution.

4. Use Windows 10 Update Assistant 

The Windows 10 Update Assistant is official software released by Microsoft which helps users update their Windows to newer versions. Not only does it allow you to update your Windows, but it also fixes any errors which could prevent the installation of the update. 

So the next solution to this error is to download and run the Windows 10 Update Assistant by following the steps below:

  1. Open your internet browser and visit this website. 
  2. Click on the “Update Now” button to download the .exe file of the Windows 10 Update Assistant.

  5. Click on the “Update Now” button in the assistant menu.
    Updating Windows using the Windows 10 Update Assistant
    Updating Windows using the Windows 10 Update Assistant
  6. Wait for the update to install.

5. Use Windows Media Creation Tool

The Windows Media Creation Tool is another software released by Microsoft which is designed to help users install and/or upgrade Windows. It works similarly to the Windows 10 Update Assistant, as it checks for errors in your current version of Windows before upgrading to the latest version. 

Using the Windows Media Creation Tool to install this Windows update can possibly solve this error, so follow the steps listed below to do so:

  1. Open your internet browser and visit this website. 
  2. Click on the “Download Now” button to download the .exe file of the Windows Media Creation Tool.
    Downloading Windows Media Creation Tool
    Downloading Windows Media Creation Tool
  3. Run the .exe file.
  4. Click on Accept.
  5. Select the “Upgrade this PC now” option.
  6. Click Next.

    Selecting Upgrade Now
    Selecting Upgrade Now
  7. Wait for the update to be downloaded.
  8. Once the update is ready to install, click on the Install option at the bottom right.

An important thing to keep in mind is that when you’re on the “Ready to Install” screen, there is no need to select the “Change what to keep” option. By default, the installer will keep all of your files and applications intact, so you don’t need to worry about your data getting lost.

6. Use the .NET Framework Repair Tool

The .NET Framework Repair Tool is another proprietary Microsoft software that is used to identify and resolve errors with the Microsoft .NET Framework. 

The Microsoft .NET Framework allows different applications, services, and drivers to run on Windows. So if there’s an issue with the .NET Framework on your PC, it could be the leading cause of the installation error you’re facing. 

To ensure that your system’s Microsoft .NET Framework is free from errors, use the .NET Framework Repair Tool by following the steps written below:

  1. Open your internet browser and head to this website.
  2. Click on the “Download” button to download the .exe file of the .NET Framework Repair Tool.
    Downloading the .NET Framework Repair Tool
    Downloading the .NET Framework Repair Tool
  3. Run the .exe file.
  4. In the installer Window, put a checkmark next to “I have read and accepted the license terms” and click Next > Next > Next >Finish. 
  5. Restart your PC.

7. Perform a Clean Boot

There could be some driver or background application/service running on your computer that is interfering with the update installation process and blocking the update from being installed on your system. 

If this is the case, we can easily overcome this issue by performing a Clean Boot. When a system is Clean Booted, it is launched with only the most crucial drivers, applications, and services. This ensures that no non-essential driver/app/service is launched on boot.

Follow the steps written below to perform a Clean Boot:

  1. Press Windows Key + R at the same time to open the Run Dialog Box.
  2. Type msconfig and press enter.
    Opening Services
    Opening Services
  3. In the Services tab, put a checkmark next to the “Hide all Microsoft Services” option.
    Hiding Microsoft Services
    Hiding Microsoft Services
  4. Disable all non-essential services.
  5. Click Apply > OK.
  6. Restart your PC.

After your PC restarts, open the Windows Update menu and install the update. If the update still doesn’t install, it means that the drivers and apps on your PC were not interfering with it. In this case, move on to the final solution below.

8. Reset Windows Update Components

If none of the above methods has fixed the installation problem for you, the final solution is to reset the Windows Update Components. 

The Windows Update Components allow Windows to download and install new updates, security patches, and drivers. These components are entirely responsible for installing Windows updates, so if there are any issues present with the components themselves, you will encounter errors when installing the updates.

So, to ensure there are no issues with the Windows Update Components, follow the steps listed below to reset them to their default settings:

  1. Press Windows Key, type Notepad, and press enter.
    Opening Notepad
    Opening Notepad
  2. Copy the following commands and paste them into Notepad:

    regsvr32.exe /s atl.dll 
    regsvr32.exe /s urlmon.dll 
    regsvr32.exe /s mshtml.dll 
    netsh winsock reset

    Sfc /ScanNow 
    net start bits 
    net start wuauserv 
    net start msiserver 
    net start cryptsvc 
    net start appidsvc
  3. Click on the “File” option in the top-left corner of Notepad and select “Save As.”
