There have been errors in the Windows operating system since its inception. They occurred in almost all versions. It looks different. An error message pops up, a "blue screen of death" is displayed, the application crashes or the system reboots altogether. In most cases, this is due to a violation of the integrity of system and important files. But the causes of such consequences can serve as a virus attack, as well as the general clogging of the system and failures.
Starting with Windows 2000, a mechanism was implemented inside it that made it possible to check the integrity of important files with the possibility of their recovery. The utility name is SFC. The best known application is SFC / scannow. What this command is and what it is used for will be described in detail in this article.
