Since the problem may occur due to a corrupt recovery image or system files, it’s best to run DISM and SFC commands to fix the ‘Reset this pc required files are not trusted’ error. Where DISM (Deployment Image Servicing and Management) repairs the Windows images used for Windows PE, RE, and Windows Setup, running SFC (System File Checker) will replace the damaged or corrupt system files with their correct versions.

- Open Command Prompt from Windows Search and run it as administrator.
- In the elevated window, type the following DISM commands and hit Enter after running each command.
DISM /Online /Cleanup-Image /CheckHealth
DISM /Online /Cleanup-Image /ScanHealth

- Once the scan is done, run the sfc/scannow command and hit Enter.
Let the process complete, and once done, check if you encounter any of the following messages on the screen:
| Windows Resource Protection did not find any integrity violations – This message means there is no missing or corrupted system file. |
| Windows Resource Protection could not perform the requested operation – This message indicates an issue with system files. Run SFC in safe mode and ensure that the PendingDeletes and PendingRenames folders are under %WinDir%\WinSxS\Temp. |
| Windows Resource Protection (WRP) found corrupt files but couldn’t fix some of them – This message means that the SFC and WRP scan found the corrupted files but could not repair some of them. |
