I have a problem on my Windows 8.1 PC where it displays a BSoD that says CRITICAL_PROCESS_DIED. I saw a page and it says that I have to run sfc /scannow. I went to the automatic repair and got to the Command Prompt. I started sfc /scannow and on the verification process, it gets to 100% then it said, "Windows Resource Protection could not perform the requested operation". How can I fix this?

to tell Windows to scan the files of the installed Windows, not the current booted WinPE.
