Use the sfc command to automatically repair Windows 7 problematic system files

If you find a problematic system file through the above tool, what should I do? In addition to repairing system files through the system installation disk or manually repairing files, another useful tool is provided in the operating system, the sfc command. The function of this command is similar to the function of the file signature authentication tool, which verifies the legality of the system files and the signature of the driver. However, there are still big differences between the two tools.

One is the difference in appearance. Sfc is a tool under the command line, that is, there is no graphical management wizard. The file signature verification tool is a graphical management tool. So in terms of convenience, the file signing tool may be easier to use. However, for system management experts, there may be no essential difference between a graphical interface and a text interface. Another major difference may be the difference in functionality. The Sfc command not only checks the legality of system files and driver signatures, but also automatically fixes detected files. The way to fix it is to automatically replace any detected incorrect files with Microsoft files. Since there is no prompt to the system administrator during the replacement process, there is a certain risk when using this tool. To this end, the author's suggestion is that the system administrator should first use the file signing tool to check which problematic system files or driver files exist. If you confirm that these files are replaced by Microsoft versions of the file without problems, use the sfc command line tool to automatically fix the problematic file.

If you are in the operating system, the system administrator has deployed some unsigned system files. If the system administrator thinks these files are required, then it is best not to use this tool. If you can use this tool, copy the files that are legal but not signed, and then use this tool to fix other problematic system files or drivers. Wait until the repair is complete before restoring these legal unsigned files or driver files. In addition, because this tool is relatively risky to run, for this reason, the Windows7 operating system has strict restrictions, and it must be an administrator to run this program. Note the default administrator account for this admin trait system. That is, if the system administrator has created a new account, then add this account to the administrators group. At this point the account has the identity of an administrator, but it still cannot run this sfc tool. Because he is not the system's default administrator account. Microsoft's restrictions in this regard are mainly to prevent this tool from being abused, thus affecting other users' applications.

You can also use this tool in conjunction with Group Policy. This tool can be run automatically when the operating system is started, as configured in Group Policy. In general, if the Windows 7 operating system is only used as a client, then this is a good choice to maintain its stability. But if it is used as a server, then I don't recommend it. Because the server is sensitive to enterprise information applications (the server is down for all related applications, the client will be affected), so use this tool only if the system file is damaged or the driver has problems. And before using this tool, it is best to use the signature verification tool to query for files that may be problematic. If necessary, you need to back up the data in the server first. To prevent the operating system from starting due to a file recovery failure. For this reason, the author thinks that sfc is a good tool to maintain system file stability, but system administrators still need to use it cautiously.
