SFC is a command-line tool that checks that all of the files covered by system file protection are as they should be, and tries to repair those that are not. Because many of those sources are on your hard disk, malware authors attempt to replace or damage them all to prevent the repair process from working. If it fails to have the expected information, it will be skipped. In all cases, the repair process also checks that the copy itвЂ™s restoring is correct. In addition, many systems include a copy of Windows on a restore or recovery partition, and, when all else fails, the original Windows installation media might be used.

Malware is the primary reason system file protection exists.Unfortunately, вЂњwrongвЂќ can be the result of many different things: If they donвЂ™t, something is wrong, and Windows will likely report the error. When files are вЂњofficiallyвЂќ updated, this information is also updated to reflect the new official files.Д®very so often, Windows checks all those files to make sure they still match, meaning the time stamp, size, and hash value all match what is expected. The premise behind system file protection is that Windows keeps information for critical files - possibly including, but not limited to, the date/time stamp of the file, its size, and its cryptographic hash. Run SFC by entering вЂњSFC /scannowвЂќ in an admin Command Prompt or PowerShell. If an unexpected version is found, SFC attempts to restore it from copies or original installation media.
