How to Fix Corrupted Files in Windows 10

In this tutorial, we are going to see how to fix corrupted files in Windows 10. Some Windows functions do not work properly anymore or Windows crashes without warning? Then the System File Checker (SFC) tool can help you! This tool allows you to analyze the Windows system files and repair the missing or damaged ones, and thus get Windows back to work. This will probably allow you to avoid a Windows repair that can take quite some time.
 

What is the System File Checker (SFC)?

The SFC is a tool that runs on the command line. Once executed, it will perform an analysis of system files that may be corrupted or damaged. Once found, the tool will then attempt to repair the damaged files. If the tool succeeds in repairing them, the user will not be forced to reinstall the entire operating system.
 
 

How to Fix Corrupted Files in Windows 10

Depending on your version of Windows, you can choose to run the SFC tool either in PowerShell or in Command Prompt (in administrator mode). In this example, We are going to use the Windows 10 PowerShell.
 

 
Step 1: To check this, type PowerShell in the Windows search bar. Then right-click on Windows PowerShell and Run as administrator.
 

 
Step 2: In the PowerShell window, type the following command, then press Enter:

sfc /scannow

 
Do not close the PowerShell window until the check is complete. The scan results will be displayed after this process is complete.
 

 
When the process is complete, one of the following messages may appear:

• Windows Resource Protection did not find any integrity violations. This means that no system files are missing or damaged.
• Windows Resource Protection found damaged files and was able to repair them. Details are provided in the log CBS.Log %WinDir%\Logs\CBS\CBS.log.

 
In case your version of Windows is corrupted in such a way that booting the operating system is impossible, you still have other methods to run the system file checker.

The first method is to start Windows in Safe Mode and from there launch the command prompt.

The second method is to run the system file checker using another Windows machine. To do this, you need to connect the hard disk with the corrupted version of Windows to another working Windows machine.
