sfc

SFC (System File Checker) is a command line tool available in Windows operating systems that allows users to scan and repair corrupted or missing system files. It helps to maintain the stability and integrity of the Windows system. The tool is primarily utilized to fix issues related to system file corruption, resulting in various problems like crashes, blue screen errors, and software malfunctions. Running the command "sfc /scannow" initiates the scanning process, and SFC checks for the integrity of system files against a cached copy stored in the Windows folder. If any discrepancies are found, it replaces the damaged files with a healthy copy from the Windows component store or, in some cases, prompts the user to insert the Windows installation media. SFC can be a useful troubleshooting tool, as it often helps resolve issues caused by corrupt system files without the need for extensive manual intervention. However, in more severe cases, additional steps might be required to completely resolve the problem.
