How to Fix KB5018482 Update Not Installing Issue in Windows 10?

The Windows 10 KB5018482 update is an optional update that resolves different bugs present in the OS. But many users have reported that they encountered various errors while trying to install this update, so it fails to install on their system properly. These installation errors can be caused by many factors, but the main cause is most likely corrupted files in the OS.

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.

   

3. Click on the “Troubleshoot” option from the list of options on the left side of the Window.
4. Select “Additional troubleshooters.”
   

   

5. Click on “Windows Update.”
6. Select the “Run as troubleshooter” option.

   

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.

   

2. Navigate to the Virus & Threat Protection category.
3. Select the blue “Open App” button.

   

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.

   

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.

   

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.

   

3. Navigate to the “Services” tab.
4. Located the “Windows Update” service and remove the checkmark next to it before pressing Apply.

   

5. Open File Explorer and go to the following path:

   C:\Windows\SoftwareDistribution

6. Delete the contents of the SoftwareDistribution folder.

   

7. Open the Services Window again and re-enable the Windows Update service.
8. Press Windows Key, type Powershell, and select “Run as administrator.” 

   

9. Type the following command in Windows Powershell and press enter:

   dism /online /cleanup-image /restorehealth

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.

   

3. Run the .exe file.
4. Wait for the assistant to check for updates.
5. Click on the “Update Now” button in the assistant menu.

   

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.

   

3. Run the .exe file.
4. Click on Accept.
5. Select the “Upgrade this PC now” option.
6. Click Next.
   

   

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.

   

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.

   

3. In the Services tab, put a checkmark next to the “Hide all Microsoft Services” option.

   

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.

   

2. Copy the following commands and paste them into Notepad:

   SC config trustedinstaller start=auto 
   net stop bits 
   net stop wuauserv 
   net stop msiserver 
   net stop cryptsvc 
   net stop appidsvc 
   Ren %Systemroot%\SoftwareDistribution SoftwareDistribution.old 
   Ren %Systemroot%\System32\catroot2 catroot2.old 
   regsvr32.exe /s atl.dll 
   regsvr32.exe /s urlmon.dll 
   regsvr32.exe /s mshtml.dll 
   netsh winsock reset 
   netsh winsock reset proxy 
   rundll32.exe pnpclean.dll,RunDLL_PnpClean /DRIVERS /MAXCLEAN 
   dism /Online /Cleanup-image /ScanHealth 
   dism /Online /Cleanup-image /CheckHealth 
   dism /Online /Cleanup-image /RestoreHealth 
   dism /Online /Cleanup-image /StartComponentCleanup 
   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.”
   

   

4. Name the file Wufix.bat and set the file type to “All Files.”
   

   

5. Save the file on your desktop.
6. Go to your desktop, right-click on the file, and select “Run as administrator.”
   

   

7. Wait for the Windows Update Components to be reset.

After a few minutes, the Windows Update Components will be reset on your system. After the process is completed, restart your PC and update your Windows. The installation error should finally be fixed.
