What command is used in Windows to check the status of system files?

The command used in Windows to check the status of system files is "sfc /scannow." This command stands for System File Checker, which scans the integrity of all protected system files and replaces corrupted or missing files with the correct versions from the Windows operating system cache. It's a key tool for troubleshooting issues related to system stability, file corruption, and ensuring that the operating system is functioning correctly. Running this command can be particularly useful when experiencing errors or instability in Windows, as it repairs system files that may have been altered or damaged.

Other commands listed serve different purposes. For instance, "chkdsk" is used to check the integrity of disks and fix logical file system errors. The "dir" command displays a list of files and directories in a specified directory, while "ipconfig" is used to view and manage network configuration settings. Each command has its distinct function, making "sfc /scannow" the appropriate choice for checking system file status.
