Fix Your Device Is Missing Important Security and Quality Fixes Error in Windows

Windows updates are essential for keeping your computer safe, stable, and running smoothly. But sometimes, instead of installing updates, you’ll see the error: “Your device is missing important security and quality fixes.”

This message usually appears when your PC hasn’t been updated for a while, an update is broken, or certain system files are corrupted. The good news is that this issue is fixable with a few practical steps.

Why This Error Appears

The error basically means your PC is not up to date with required Windows updates. Some common reasons include:

• A recent update was broken or didn’t install properly
• Corrupt or missing system files
• Outdated servicing stack updates
• Third-party programs interfering with the update process
• Malware infections
• Telemetry settings set to “security-only,” which can block updates

How to Fix the Error

1. Run the Windows Update Troubleshooter

Windows has a built-in troubleshooter designed to detect and fix update issues.

• Open Settings (Win + I)
• Go to Update & Security > Troubleshoot (Windows 10) or System > Troubleshoot > Other troubleshooters (Windows 11)
• Select Windows Update and run the troubleshooter
• Follow the on-screen instructions and restart your PC

2. Reset the Windows Update Folder

Corrupt update files stored in the SoftwareDistribution folder can cause this error. Resetting it usually helps.

• Open Command Prompt as Administrator
• Run these commands one by one (press Enter after each):

net stop wuauserv
net stop bits
net stop cryptsvc
net stop msiserver
ren %systemroot%\SoftwareDistribution SoftwareDistribution.old
ren %systemroot%\system32\catroot2 catroot2.old
net start wuauserv
net start bits
net start cryptsvc
net start msiserver

• Restart your PC and try updating again

3. Repair System Files

If system files are damaged, Windows may not update properly. You can repair them with built-in tools.

• Open Command Prompt as Administrator
• Run these commands:

DISM /Online /Cleanup-Image /RestoreHealth
sfc /scannow

• Restart your computer after the scans are done

4. Reinstall Recent Updates

Sometimes a faulty update is the culprit. Removing and reinstalling it can solve the problem.

• Search for Update history in the Start menu
• Open View update history > Uninstall updates
• Right-click the most recent update and uninstall it
• Restart your PC, then check for updates again

5. Adjust Telemetry Settings

Some updates require Telemetry (data sharing with Microsoft) to be enabled.

• Press Win + R, type gpedit.msc, and press Enter
• Navigate to:
  Computer Configuration > Administrative Templates > Windows Components > Data Collection and Preview Builds
• Double-click Allow Telemetry
• Set it to Enabled and choose any level except 0 – Security
• Save and restart your PC

6. Use Windows Update Assistant

If nothing else works, try using Microsoft’s official Windows Update Assistant.

• Download it from Microsoft’s website
• Run the tool and click Update Now
• Follow the instructions until the process finishes

Bonus Tip: Keep Drivers Updated

Although outdated drivers don’t directly cause this error, they can create other update issues. Make sure your PC drivers are up to date, either manually from Device Manager or with trusted update tools.

Conclusion

The error “Your device is missing important security and quality fixes” can look worrying, but it usually comes down to corrupt files, a broken update, or misconfigured settings. Start with the simpler fixes like running the troubleshooter, then move on to resetting update services or repairing system files. In most cases, one of these steps will get your PC back on track with updates.
