System File Corruption solution in CMD

If you suspect system file corruption in your Windows operating system, you can use the System File Checker (SFC) tool to scan and repair corrupted system files. Here’s how you can do it:

1. Open Command Prompt as Administrator:
   • Right-click on the Start button (Windows icon) and select “Command Prompt (Admin)” or “Windows PowerShell (Admin).”
   • If you’re using Windows 10, you can also search for “Command Prompt” or “PowerShell,” right-click on the result, and choose “Run as administrator.”
2. Run the System File Checker (SFC):
   • In the Command Prompt window, type the following command and press Enter:shellCopy codesfc /scannow
   • This command will initiate the scanning process for corrupted system files.
3. Wait for the Scan to Complete:
   • The System File Checker will now scan protected system files and replace corrupted or modified versions with the correct Microsoft versions. This process may take some time, so be patient.
4. Review the Scan Results:
   • After the scan is complete, you will receive one of the following messages:
     • “Windows Resource Protection did not find any integrity violations.”
     • “Windows Resource Protection found corrupt files and successfully repaired them.”
     • “Windows Resource Protection found corrupt files but was unable to fix some of them.”
5. Review Detailed Log (if necessary):
   • If the scan finds and fixes corrupted files, you might want to review the detailed log for more information. You can find the log file at %windir%\Logs\CBS\CBS.log. Open it with a text editor like Notepad to see the details.
6. Run SFC in Safe Mode (if necessary):
   • In some cases, running SFC in Safe Mode may be more effective. You can restart your computer in Safe Mode and then open the Command Prompt as an administrator to run the sfc /scannow command.
7. Perform a System Restore (if necessary):
   • If the issue persists after running SFC, you may consider performing a System Restore to revert your system to a previous state when it was functioning correctly.
8. Use DISM (Deployment Image Service and Management Tool):
   • In addition to SFC, you can use the DISM tool for further repairs. In the same Command Prompt window, type the following command and press Enter:shellCopy codeDISM /Online /Cleanup-Image /RestoreHealth
   • This command attempts to repair the Windows image.
9. Reboot Your Computer:
   • After completing the above steps, it’s a good practice to reboot your computer to ensure that any changes take effect.
