In this case, if you are here, it is because you want to know How to Fix Device is Missing Important Security. So, we will explain it in detail.
If Windows Update were giving you trouble and refusing to install important security and system updates, you will see the "Your Device is Missing Important Security and Quality Fixes" notification. According to this error message, if your system isn't up-to-date with important updates, then you are leaving yourself open to being exploited. This happens quite a lot when Windows upgrades either do not successfully complete or versions of Windows reach end-of-support from Microsoft.
Important Security and Quality Fixes Are Missing from Your Device.
Update files being corrupted or network problems preventing updates from downloading correctly are two other possible causes.
Several ways to fix this mistake are covered in this article.
1. Update Windows via Update Assistant
Incomplete downloads or system errors can cause the built-in update procedure to fail, rendering your device outdated. The Windows Update Assistant saves you the headache by starting the update process directly from Microsoft's servers. This utility will guarantee that your OS is running the latest stable version, complete with recent security patches and upgrades. With this utility, updates that have either remained incomplete or were stopped and caused the problem, get resolved. Here you will find the Windows Update Assistant.

2. Run the Windows Update Troubleshooter
If this does not install an update via Windows Update, you may want to run the Windows Update Troubleshooter. It will identify a number of problems that exist, including corrupted or missing files, incorrect configurations, and deactivated update services. By fixing these, the ability of your system to connect with Microsoft's update servers enhances even more: smoother downloads, smoother application of updates.

After that check if the problem is fixed.
3. Rename the Software Distribution Folder
This could be due to corrupted or incomplete update files in the SoftwareDistribution folder. Renaming this folder will only make Windows create a new folder and get rid of those old files that could be the source of the problem with the updates. In doing so, it will save the new update information in this different location, and Windows will be able to download the necessary files once again and complete the update process without any complications from the old files.
Press Windows + S, and then right-click Command Prompt to Run as administrator. Start Administrator's Command Prompt In order to disable Windows Update, write the following and press the key: net stop wuauserv net stop bits which end net After running the script, you will be renaming the Software Distribution folder by copying the following command: You must rename the C:\Windows\SoftwareDistribution folder. save as SoftwareDistribution.bak

When that is complete, verify whether or not the problem persists during the updating of Windows.
4. Run System File Checker
If you are having problems installing updates, perform a system file check followed by using DISM to replace broken or missing system files. When those critical files have been repaired, Windows should install updates normally and the problem will be solved.
Search for "Command Prompt" in the search bar of the Start menu.
Right-click on the terminal and Run as administratorRun as Administrator
Then, copy and paste each of these commands and press Enter after each one: repair system files DISM/Online/Cleanup-Image/RestoreHealth Sfc/scannow
After verification, you should check whether the issue still exists or not.

One good example of the kind of system problem which may result from a not-so-successful update is the message "Your Device is Missing Important Security and Quality Fixes". Corrupted files or processes in state can prevent critical Windows updates from installing, which you can remove by reinstalling such updates.
