How to Fix KB5018410 Not Installing on Windows 11: Step-by-Step Solutions

Sometimes, Windows updates can fail to install properly. One common issue is with the update KB5018410 on Windows 11. This can be frustrating, especially if the update is important for your system’s security and performance.

Fortunately, there are several straightforward methods to fix this problem. These solutions range from simple system checks to more advanced troubleshooting steps.

This article will guide you through each step in an easy-to-understand way. Even if you are not very tech-savvy, you will be able to follow along and hopefully get the update installed.

Let’s start with some quick checks you should do before moving on to fixes.

Quick Note: Prerequisites and Initial Checks

Before you begin troubleshooting, make sure you have the following:

  • Stable Internet Connection: Updates need a reliable internet connection to download files correctly.
  • Enough Disk Space: Windows updates require free disk space. At least 10 GB of free space is recommended.
  • Power Supply: If you are on a laptop, connect it to power to avoid interruptions during the update.
  • Pause Other Activities: Close unnecessary apps to free system resources.

Step 1: Restart Your Computer

Sometimes, a simple reboot can fix update problems. Restarting clears temporary files and refreshes system processes.

  1. Click on the Start menu.
  2. Select Power and then click Restart.
  3. After the computer restarts, try installing the update again by going to Settings > Windows Update > Check for updates.

If the update still does not install, proceed to the next step.

Step 2: Run the Windows Update Troubleshooter

Windows has a built-in tool that automatically detects and fixes common update issues. Running this troubleshooter is an easy next step.

  1. Open Settings by pressing Windows + I.
  2. Go to System > Troubleshoot > Other troubleshooters.
  3. Find Windows Update and click Run.
  4. Wait for the troubleshooter to detect problems and apply fixes.
  5. Once complete, restart your computer and try updating again.

Step 3: Clear the Windows Update Cache Manually

Sometimes, corrupted cache files can block updates. Clearing this cache forces Windows to download fresh update files.

  1. Press Windows + S, type cmd, right-click Command Prompt, and select Run as administrator.
  2. In the command window, type the following commands one by one, pressing Enter after each:
net stop wuauserv
net stop bits

These commands stop the Windows Update services temporarily.

  1. Now, open File Explorer and navigate to C:WindowsSoftwareDistribution.
  2. Delete all files and folders inside the SoftwareDistribution folder. This clears the update cache.
  3. Return to the Command Prompt and type these commands to restart the services:
net start wuauserv
net start bits

Close the Command Prompt, restart your PC, and try the update again.

Step 4: Check System Files for Corruption

Corrupted system files can prevent updates from installing properly. You can use built-in tools to scan and repair these files.

  1. Open Command Prompt as an administrator (see Step 3).
  2. Type the following command and press Enter:
sfc /scannow

This System File Checker will scan for issues and repair them automatically. This process may take some time.

After it finishes, restart your computer and attempt the update again.

Step 5: Use the DISM Tool to Repair Windows Update Components

If the problem persists, the Deployment Image Servicing and Management (DISM) tool can fix deeper Windows image problems.

  1. Open Command Prompt as administrator.
  2. Run the following commands one at a time, pressing Enter after each:
DISM /Online /Cleanup-Image /CheckHealth
DISM /Online /Cleanup-Image /ScanHealth
DISM /Online /Cleanup-Image /RestoreHealth

These commands check for corruption and repair the Windows image. The last command may take several minutes to complete.

Once done, restart your PC and try installing the update again.

Step 6: Manually Download and Install the Update

If automatic installation fails, you can download the update package manually from the Microsoft Update Catalog.

  1. Open your web browser and visit the Microsoft Update Catalog.
  2. Search for “KB5018410” in the search box.
  3. Find the update matching your Windows 11 version and system type (x64 or ARM64).
  4. Click Download and save the file to your computer.
  5. Once downloaded, double-click the file to start the manual installation.

Follow the on-screen instructions and restart your PC if prompted.

Alternative Method: Reset Windows Update Components Automatically

If you prefer an automated solution, Microsoft provides scripts that reset Windows Update components. These scripts remove possible blocks and fix service issues.

You can find official reset scripts on Microsoft’s support website or use trusted third-party tools. Always ensure you download scripts from reliable sources to protect your system.

Frequently Asked Questions (FAQs)

Why does KB5018410 fail to install?

Will skipping this update affect my system?

Updates often contain security patches and bug fixes. Skipping important updates can leave your system vulnerable or unstable.

When Nothing Works

If none of the above solutions resolve the issue, you can try these final options:

  • Use System Restore: Roll back your system to a point before the update problem began.
  • Reset Windows 11: This reinstalls Windows without affecting your personal files but removes installed apps.

These steps should be used carefully, as they can affect your system setup.

Conclusion

Fixing the KB5018410 update installation issue on Windows 11 is usually possible by following simple troubleshooting steps. Starting with a restart and running the Windows Update troubleshooter can solve many problems quickly.

Clearing the update cache, checking system files, and using DISM are effective ways to fix more complex issues. If needed, manually downloading the update provides a reliable alternative.
