Corruption in system files can take place under numerous circumstances, like improper system shutdown, virus infection, and operating system malfunction. Windows Vista is embedded with a powerful utility – SFC (System File Checker) – that provides complete check of missing and damaged system files. To run SFC utility, the user needs to log on as an administrator. While in most cases, the utility repairs the corrupt system files, there is no guarantee that the command will always succeed in performing the task.

In situations where the command fails to repair the system files, it logs all its actions to a log file saved at C:\WINDOWS\LOGS\CBS. The files mentioned in the CBS.LOG file need to replaced if the user needs to boot his/her Windows Vista based system. However, if the user is unable to do so, then the only option is to reinstall Windows Vista. To recover files post fresh reinstall of Windows Vista, the user needs to opt for an effective <a href="/">windows data recovery</a> software.

but was unable to fix some of them.
