What is the system file check engine

The File System Checker, also known as the sfc.exe is a utility that has been with the Windows OS since Windows 98, although it served a different purpose compared to today.

Starting with Windows Vista, the System File Checker was introduced to Windows Resource Protection (WRP), allowing it to protect not only standard data, but also records, and essential system files.

Windows users today can use the File System Checker to scan for any data that may have been destroyed or erased as a result of malware, corruption or user abuse and bring it back.

How is sfc / scanow Work?

Ever since the SFC was introduced into the WRP, any changes applied to any of the main Windows system files by the SFC will be detected, and the modified file will be updated using semi- a backup copy that is located in the Windows folder itself.

Because of this, every time you encounter any kind of data loss or corruption, it is best to use this tool first, before doing a real System Update.

How do I run an System file checker?

The System File Checker has been made very easy to access and use, especially since you are expected to use it in situations where many of Windows’ advanced functions may no longer be available.

So, here ‘s how to trigger a full scan of File System Checker:

  1. Press the Windows key until the Start menu
  2. Enter cmd and launch the Prompt Command using Run as administratorHow to run system file checker
  3. Depending on what you want the SFC to do, you can add one of these 2 lines in the Command Prompt:
  • sfc /scannow
    • Use this if you want the SFC to find and repairs any missing or corrupted data
  • sfc /verifyonly
    • Use this if you want the SFC to find any missing or corrupt data

Once you have started running one of these scans, all you have to do is wait for your PC to go through all the data stored on it.

Keep in mind that since the SFC scans your entire PC, PCs with larger storage and more data will last longer, compared to PCs with very little saving.

CONCLUSION: File System Checker

That’s almost everything there is about System Checker.
