sfc 示例
sfc /scannow
开始扫描所有系统文件。
sfc /VERIFYFILE=c:\windows\system32\kernel32.dll
检查kernel32.dll文件是否存在任何问题。如果扫描文件没有发现问题，则“ Windows资源保护未发现任何完整性违规”。几秒钟后出现此消息。
sfc /scannow
Begins the scan of all system files.
sfc /VERIFYFILE=c:\windows\system32\kernel32.dll
Check the kernel32.dll file for any problems. If no problems are found with the file scanned a "Windows resource protection did not find any integrity violations." message appears after a few seconds.
在Windows Vista，Windows 7，Windows 8和Windows 10中，必须在管理员的命令模式下运行，SFC命令才能正常工作。否则，您将收到“您必须是运行控制台会话的管理员才能使用sfc实用程序”。尝试运行以下任何示例时出现错误。
In Windows Vista, Windows 7, Windows 8, and Windows 10 you must be running in an elevated command mode for the SFC command to work properly. Otherwise, you'll receive the "You must be an administrator running a console session to use the sfc utility." error when you attempt to run any of the following examples.
