Win10: How To Run The System File Checker (SFC) Windows 10

APPLIES TO:

Windows 10

HOW TO:

If Windows is not functioning properly or crashes the System File Checker can be used to fix file corruption of the Windows Operating System

RESOLUTION:

Step 1: Open an elevated command prompt. To do this, right click Start, and select Search in the Search dialog box type in Command Prompt or cmd. In the resulting box, right-click Command Prompt, and then click Run as administrator. If you are prompted for an administrator password or for a confirmation, type the password, or click Allow.

Step 2: At the command prompt, type the following command, and then press ENTER: sfc /scannow  (Note: the space after sfc)

The sfc /scannow command will scan all protected system files, and replace corrupted files with a cached copy.

Once the System Filer Check has completed your message may be: 
Windows Resource Protection found corrupt files and successfully repaired them. Details are included in the CBS.log windir\Logs\CBS\CBS.log. For example c:\Windows\Logs\CBS\CBS.log. 

If this is your message run the System File Checker again until you get the following message:
Windows Resource Protection did not find any integrity violations.
Finished.

If you get the message: 
Windows Resource Protection found corrupt files but was unable to fix some of them. Details are included in the CBS.Log  winDir\Logs\CBS\CBS.log.

Then open the command prompt and run the following command. 

DISM.exe /Online /Cleanup-image /Restorehealth
