Fix 1: Repair corrupted system files
This error message could be triggered by corrupted system files. In most cases, you can fix system file corruptions by running the system file checker tool.
To do this, follow these steps:
- Press the Windows logo key and R on your keyboard to invoke the Run box.
- On your keyboard, type cmd and press Ctrl, Shift and Enter at the same time to run Command Prompt as administrator.
- You’ll be prompted for permission. Click Yes to open Command Prompt.
- Type sfc/scannow, then press Enter.
- The System Files Checker tool will automatically scan for corrupt or missing files and fix them, if there’s any.
Restart your PC to see if the issue persists.
If you’re still seeing the error message, try the next fix.
Fix 2: Run Windows Updates troubleshooter
Another quick fix that you can try is to let Windows diagnose the problem for you. Below are the steps to run the Windows Updates troubleshooter:
Windows 10:
- Press the Windows key and I on the keyboard to open the Settings window.
- Click Update & Security.
- Select Troubleshooter in the left pane, and click Additional troubleshooters.
- Select Windows Update, then click Run the troubleshooter.
- Wait for the diagnosis to complete, and follow the instructions to fix the problems if applicable.
Windows 11:
- Press the Windows key and I to open Settings.
- Click System on the left pane, then scroll down on the right pane and select Troubleshoot.
- Click Other troubleshooters.
- Under the Most frequent section, find Windows Update and click the Run button.
- Wait for the diagnosis to complete, and follow the instructions to fix the problems if applicable.
Check for Windows Updates again to see if the error message is gone now. If this doesn’t help, try the next fix.
Fix 3: Reinstall the most recent Windows security updates
Another possible cause of this error is a previous broken Windows update. You can try to manually uninstall and then reinstall the most recent Windows security update. This fix is most likely to work when the error is triggered by a recently installed Windows update. Here’s how to do it:
- In the search bar next to your Start button, type in update history, then click View your update history.
- You should find the history of security and quality updates here (if applicable). Mark down the most recently installed update, and click Uninstall updates above.
- Find the most recent update, right-click it then click Uninstall.
- After the most recent Windows update is removed, reboot your PC.
- Check for Windows updates again then reinstall the available updates.
If this doesn’t resolve the error, move on to the next fix.
Fix 4: Reset Windows Updates services
The error “your device is missing important security and quality fixes” may indicate that your Windows updates service components are corrupted. You can manually reset them via Command Prompt. Below are the explanation and step details:
1) First, we’ll stop the services that are required for Windows Updates to download and install updates.
2) Then, we’ll delete the Software Distribution folder in which Windows Updates stores the temporary files. It’s safe to delete this folder because Windows will detect it when it’s missing, then create a new one. In this way, any possible issues from the old folder can be avoided.
3) Lastly, we’ll restart the services that we stopped previously.
- In the search bar next to the Start button, type in command prompt, then click Run as administrator. If prompted for permission, click Yes.
- Copy and paste the following commands into the Command Prompt window. Make sure you do it one at a time, and press Enter for every command to run.
- net stop wuauserv
- net stop bits
- net stop appidsvc
- net stop cryptsvc
- In the Command Prompt window, copy and paste Ren %systemroot%\SoftwareDistribution SoftwareDistribution.old, then press Enter.
- Copy and paste these command lines one by one in Command Prompt. Press Enter after you paste every single command for it to run.
- net start wuauserv
- net start bits
- net start appidsvc
- net start cryptsvc
You can now check for Windows Updates to see if the error is gone. If not, there’s one more fix you can try.
Fix 5: Enable the Telemetry settings
If the fixes above don’t work, you can try to enable the telemetry settings. Microsoft Compatibility Telemetry collects data on how your PC and the software are running and sends the data to Microsoft. If the Telemetry setting is not allowed or set to “security-only”, some Windows updates may not be able to deliver. Here’s how to change the Telemetry level:
- Press the Windows key and R to invoke the Run box.
- Type in gpedit.msc, then click OK.
- Go to Computer Configuration >> Administrative Templates >> Windows Components >> Data Collection and Preview Builds.
- Double-click Allow Telemetry.
- Select Enabled and change the Telemetry level as long as it’s NOT 0 – Security. Once done, click Apply and then OK to save the changes.
Bonus tip: Update your device drivers
Outdated or faulty drivers may trigger this error, although not very common. But in general, keeping your device drivers up-to-date can help prevent and solve many random computer issues.
There are two ways to keep your drivers up-to-date. One is to update the drivers via Device Manager. You may have to manually check every device and update them when Windows detects available updates.
Automatic driver update – If you don’t have the time, patience, or computer skills to update your drivers manually, you can do it automatically with Driver Easy. Driver Easy will automatically recognize your system and find the correct drivers for your PC and your Windows version, and it will download and install the drivers correctly:

Summary
- To fix your update issue, download and run the Windows Update Assistant, install the available updates, and reboot your PC.
- Other methods to resolve the problem include deleting your Windows Update cache, using Windows Update troubleshooter, and repairing Windows’ corrupted system files.
If you’ve encountered a “Your device is missing important security and quality fixes” error on your Windows 10 computer’s Windows Update screen (like I did), worry not, as you can use Windows Update Assistant to fix your problem. There are other ways to resolve this issue, and we’ll show you how to apply them.
1. Use Windows Update Assistant
The easiest way to fix your update error is to use Windows Update Assistant. This official Microsoft tool downloads and installs the latest system updates for you. After updating your PC to the latest Windows version with this tool, your future updates will work just fine.
To use the tool, head to the Windows Update Assistant web page. Here, click «Update Now» to download it.
Run the downloaded tool file, install the updates displayed in the tool, and restart your PC.
In the future, you can update your system from Settings > Update & Security > Windows Update as usual without encountering the above error.
2. Clear Your Windows Update Cache
If your downloaded update files are corrupted, that can cause issues updating your system. In this case, clear your Windows Update cache, and your issue should be resolved.
Windows will re-download any required update files, so you don’t lose anything permanently when you clear your update cache.
To start, launch the Run dialog box by pressing Windows+R. Here, type the following command and press Enter:
services.msc
On the «Services» window, find the service named «Windows Update». Right-click it and choose «Stop». You’re doing this because Windows won’t let you delete your update files if this service is running. Keep the «Services» window open, as you’ll return to it shortly.
Now, open the Run dialog box again, enter the following in the field, and press Enter:
C:\Windows\SoftwareDistribution\
You’ll see your Windows Update cache folder. Here, select all available files by pressing Ctrl+A. Then, right-click a selected file and choose «Delete». This deletes all your update cache files.
Make sure to empty your Recycle Bin after deleting the above files. Then, return to the «Services» window, right-click «Windows Update», and select «Start».
To now update your PC, head into Settings > Update & Security > Windows Update and find and install the available updates.
3. Use the Windows Update Troubleshooter
If your issue persists, something else may be wrong with Windows Update. In this case, use your PC’s built-in Windows Update troubleshooter to automatically find and fix issues with your updates. Only a little interaction is required from your end.
To run that tool, go to Settings > Update & Security > Troubleshoot > Additional Troubleshooters > Windows Update and click «Run the Troubleshooter».
Wait for the tool to detect and resolve your update problems. This can take anywhere from a few seconds to a few minutes, then restart your PC.
4. Fix Windows’ Corrupted System Files
If Windows’ core files are corrupted, that can cause your various system features to malfunction, including Windows Update. In this case, use your PC’s built-in SFC (System File Checker) tool to find and repair all the damaged system files on your computer.
To use the tool, open your PC’s Start Menu, find «Command Prompt», and select «Run as Administrator».
In the «User Account Control» prompt, choose «Yes».
On the Command Prompt window, type the following command and press Enter. This will download the files needed to fix your corrupted files.
DISM.exe /Online /Cleanup-image /Restorehealth
Next up, run the following command to begin finding and fixing your system’s damaged files:
sfc /scannow
Wait while the command does its job, then reboot your PC.
And that’s how you resolve the “Your device is missing important security and quality fixes” error.
