How to Fix “Your device is missing important security and quality fixes” Error on Windows 10?
Using the Windows 10 Update Troubleshooter
The first thing to try in case of any problems with Windows updates would be the built-in Windows Update Troubleshooter. This handy tool from Microsoft can detect most problems, if any, with relative ease and fix them automatically. In case the problems are too severe, you may have to move on with the other methods to fix this problem.
- Press the “Windows Key + I” shortcut on your keyboard together to bring up the System settings of Windows 10.
- Navigate to “Updates and Security” from the home screen of the Settings app.
- From the left navigation pane, choose “Troubleshoot”

Note that this method will fix most basic issues with the Windows Updater. But, in case the underlying cause of your problem is more severe and the troubleshooter reports that it couldn’t find any solutions, then you should move on to the next steps.
Installing the Most Recent SSU (Servicing Stack Update)
SSU or Servicing Stack Updates are essential to the proper working of Windows 10. These are basically updates to the updater component of Windows and missing these can cause the aforementioned problem to arise. To fix this by installing the latest service stack for your OS build, follow these steps.
- Press the “Windows Key + R” shortcut on your keyboard to bring up the “Run” popup.
- Type in “Winver” without quotes and press Enter.
- A pop-up with the exact build number of the OS version you’re running should come up. Note the build version for later use.
- Open this official Microsoft link that lists all the latest SSUs and the versions they are compatible with.
- From the table, note down the relevant SSU Package name for your OS build and visit the Microsoft Update Catalog.
- Once you’re on the Microsoft Update Catalog homepage, enter the SSU package number on the search box.
- From the results that come up, download the most relevant one and install it by running the package as an administrator.
- Reboot and try to continue updating your system as usual.
This method should fix any underlying issues with the Microsoft servicing stack update, which causes the aforementioned issue in most cases. If this method still doesn’t work for you, this may be a sign that some critical system files have been damaged.
Repairing Critical System Files
One of the easiest ways to fix any missing or corrupted system files that don’t directly affect the working of the OS is to use a few commands in the Windows terminal. Let’s take a look at how to do so, step-by-step.

- After the process completes all background work, restart your PC and try to run the Windows Updates again.
