3. Repair Corrupted Windows Files using DISM¶

Corrupted system files are a common cause of various Windows errors, including security setting issues. The Deployment Image Servicing and Management (DISM) tool is a powerful command-line utility that can be used to scan for and repair corrupted system files. DISM can utilize Windows Update to obtain replacement files, or it can use a local Windows installation source.

To repair corrupted Windows files using DISM:

1. Open Command Prompt as Administrator: As before, open Command Prompt with administrative privileges by pressing Windows key + R, typing cmd, and pressing Ctrl + Shift + Enter.

2. Run DISM RestoreHealth Command: In the elevated Command Prompt, type the following command and press Enter:

   DISM.exe /Online /Cleanup-image /Restorehealth
   

   This command instructs DISM to scan for corrupted files, connect to Windows Update online to download replacement files, and repair any detected corruption. Ensure you have a stable internet connection during this process.
   3. Wait for the Process to Complete: The DISM scan and repair process can take a considerable amount of time, depending on the extent of the corruption and your internet speed. Do not interrupt the process. The Command Prompt window will display progress indicators.
   4. Alternative Source for Repair (If Windows Update Client is Broken): In some cases, if your Windows Update client itself is corrupted, DISM might fail to obtain files from Windows Update. In such scenarios, you will need to provide an alternative repair source, such as a mounted Windows ISO image or a network share containing Windows installation files. If prompted, or if the above command fails, use the following command, replacing C:\RepairSource\Windows with the actual path to your repair source:

   DISM.exe /Online /Cleanup-Image /RestoreHealth /Source:C:\RepairSource\Windows /LimitAccess
   

   Important: Replace C:\RepairSource\Windows with the correct path to your Windows installation source files. This could be the drive letter of a mounted Windows ISO image or a network path. The /LimitAccess parameter prevents DISM from using Windows Update, forcing it to use the specified source.
   5. Review DISM Log File: After the DISM process is complete, it creates a log file at %windir%/Logs/CBS/CBS.log. This log file contains details of the scan and repair operations performed by DISM. You can review this log file to check for any specific issues found or fixed.
   6. Restart Your Computer: Restart your computer after the DISM process is finished.
   7. Run Windows Update Again: After restarting, try running Windows Update again to check if the “Some security settings are missing or have been changed” error has been resolved.

Using the DISM tool to repair corrupted Windows system files is a comprehensive approach to address underlying system integrity issues that may be causing the security settings error.
