SFC Type 1: What is it and how to diagnose

When Windows starts up, if you see a blue screen with text that mentions SFC type 1 or SFC type 2, it means your system file checker (SFC) found some corrupted files. This article will help you understand what these messages mean and how to fix them.

First thing is first:

What does SFC stand for? SFC stands for System File Checker, the utility in Windows that checks for corruptions of crucial operating system files like DLLs and EXEs. If SFC finds any problems, it will attempt to replace the corrupted file with an undamaged version from its backup copy on your hard drive. It sounds simple enough, but SFC can be a tricky business. When SFC finds a problem with your system files, it can be challenging to determine the cause.

Your SFC may find corruptions when you have, in fact, just downloaded or updated an EXE from Microsoft’s website and are finding false positives for this file as being corrupted, which will make you unable to repair some of the files. SFC can be run from a command prompt or be executed by opening an ” elevated Command Prompt.”
