6 Ways to Fix “Your Device is Missing Important Security and Quality Patches” Error


Installing the latest Windows updates is crucial for the overall health of your system, but the installation process isn’t always as easy as it seems. There are times when users encounter problems while doing this which is usually caused by corruption errors and temporary bugs.

In this guide, we will discuss some troubleshooting methods that have proven effective in resolving “Your device is missing important security and quality patches” error that is preventing users from updating their system. The good thing is that the methods below are not limited to fixing this error, and you can also test them in case of other similar update issues.

1. Run Windows Update Troubleshooter

One of the easiest ways to help you fix the update error is to run the Windows Update Troubleshooter. Microsoft designed this utility, and it works by scanning the system for potential problems. If it finds any issues, it will automatically fix them for you.

All the latest versions of Windows come with an update troubleshooter, but the steps for navigating to its location may be slightly different.

Here’s how to run the troubleshooter:

  1. Hurry To win + I to open Windows Settings.
  2. Move towards Update and security > Troubleshoot.
  3. Locate and click Windows Update Troubleshooter on the right side of the window under Get up and running.
  4. If you cannot find this troubleshooter, click on the Additional convenience stores and find the Update Troubleshooter in the next window.
  5. Hit it Run the troubleshooter and wait for the utility to complete its operation.
  6. If there are any issues that need to be investigated, the troubleshooter will display them in a dialog box. In this case, click on the Apply this hotfix option.
  7. Then click on Close convenience store and try to install updates again.


Hopefully the Windows Update service will work fine now.

2. Rename software distribution folder

The Software Distribution folder in Windows is where the operating system stores its Windows update files. The Windows Update Agent manages this folder, and although it does its job quietly in the background most of the time, it can sometimes prevent you from installing the latest updates.

This usually happens when the Windows Datastore folder and the Downloads folder have become incompatible.

In this method, we are going to rename the Software Distribution folder and see if that makes a difference. However, before proceeding, make sure to disconnect from your Wi-Fi connection and switch to Airplane mode. Then restart your computer.

On reboot, follow these methods:

  1. Hurry To win + R to open a Run dialog box.
  2. Type ordered in Run and press Ctrl + Shift + Enter to open the command prompt with administrative privileges. You will need to be logged into Windows as an administrator for this.
  3. Type the following commands in the Command Prompt window one by one and press Enter after each to execute them.
    net stop wuauservnet stop cryptsvcnet stop bits net stop msiserverren %systemroot%softwaredistribution softwaredistribution.bak ren %systemroot%system32catroot2 catroot2.bak net start wuauserv net start cryptSvcnet start bitsnet start msiserver
  4. Once the commands are executed, restart your PC. You can now try to install updates again.

3. Restart Windows Update Service

There is a relevant service behind every Windows process, including installing an application, using Windows Defender Firewall, and updating the system.

A problem with the Windows Update service can also prevent you from installing the latest Windows updates. Fortunately, you can fix most problems with Windows services by restarting them.

Follow these steps to reset the Windows Update service:

  1. Type Services in Windows search and click Open.
  2. In the next window, find the Windows Update Service and right click on it.
  3. Picking out Properties from the context menu.
  4. If the service is stopped, expand the drop-down menu for Startup type and choose Automatique.
  5. Then click on the Begin button and select Apply > OKAY proceed.
  6. If the service was already running, click the Stop button.
  7. Wait a few seconds, then click the Begin button. Make sure the startup type is set to Automatique.
  8. Click on Apply > OKAY to save changes.

Once done, check if following the above steps made any difference.

4. Check system files for inconsistencies

Your computer’s essential system files can also become corrupted, preventing you from using certain Windows features. This usually happens when malware and viruses infect your system.

As with the troubleshooter, Windows also includes built-in fixes for issues like this. The best course of action in the future will be to scan the system for problems using the SFC and DISM utility developed by Microsoft.

These utilities search for corrupt files in the system and then replace them with their healthier counterparts. SFC and DISM are independent tools, but they work best in coordination with each other.

We recommend that you run the SFC command on the command prompt first. After it runs, continue running the DISM command.

5. Reinstall Windows Updates

Windows updates are meant to fix issues within the system, but that’s not always the case. Sometimes broken updates can lead to issues like the one under review.

In this specific case, KB4100347 and KB4457128 seem to be the culprits. We will try to reinstall them and see if that allows you to install the latest update on Windows.

Proceed as follows:

  1. Type Control Panel in Windows search and click Open.
  2. Click on Uninstall a program.
  3. Select View installed updates of the left panel.
  4. Locate KB4100347 and KB4457128 updates. If both/one of them are present, right click on it and choose Uninstall.
  5. Once the updates are uninstalled, go to the Windows Update section of the settings.
  6. Check for these updates and reinstall them.
  7. Then try to install the updates you tried to install earlier.

6. Use Windows Update Assistant

Finally, if the troubleshooting methods don’t work for you, you can use the Windows Update Assistant to install the required updates instead of using Windows Settings.

To do this, you must first install the Windows Update Assistant. After downloading the wizard, launch it and click Yes in the confirmation prompt. In the next window, click the Update Now button.

So choose Next > Restart nowand pending updates will be installed.

Keep your system up to date

You should now be able to install updates without any issues. However, if you are still having a problem, we suggest that you contact Microsoft support officials and report the problem to them. They will help you identify the real cause and suggest fixes accordingly.
