System File Checker, also known as SFC, is an inbuilt utility software tool provided by Microsoft as part of the Windows operating system. It is used to check and repair any corrupted system files associated with the Windows operating system. It can also be used to restore missing or modified system files. The System File Checker (SFC) utility is one of the most powerful tools provided by Microsoft to help maintain the integrity of the Windows operating system.
To run the System File Checker (SFC) tool, you need to have administrative privileges. Start by opening the Run box. To do this, press the Windows key + R at the same time. Alternatively, you can search for “run” in the start menu. Once the “Run” box is open, type in “sfc /scannow” in the command window and press Enter. This command will initiate a scan of all system files.
The System File Checker will now start to scan your computer. Depending on the size of your hard drive and the number of system files it contains, this process can take several minutes. When the scan is complete, you will be presented with a report containing details of any problems that were found and fixed.
In some cases, the System File Checker might not be able to repair a particular file. In this case, you may need to use the “Windows Resource Protection” tool to restore the missing file. To use the Windows Resource Protection tool, open the Run box again, type in “rpcdll /restore” and press Enter. When the restoration process is complete, you should restart your computer for the changes to take effect.
If the System File Checker does not find any errors, it is still possible to perform a manual check of the system files. To do this, type in “sfc /verifyonly” in the command window to check the integrity of the system files. This process can take several minutes depending on the size of your hard drive. Once the scan is complete, you will be presented with a detailed report containing any discrepancies between the actual files and the backup files.
It is important to note that running the System File Checker does not affect the functionality of the operating system in any way. The tool is simply used to verify the integrity of the system files, and it does not delete or replace any corrupted files. If the problem persists after running the System File Checker, you may need to try running the Windows Resource Protection tool or performing a manual check using the sfc /verifyonly command.
The System File Checker (SFC) utility is a useful tool for keeping the Windows system healthy and error-free. Running it periodically can help ensure that your system files are working correctly, and that any corrupted files are fixed.
