Cases of the System File Checker Windows 10 Not Working
Although Windows 10 File System Checker is a useful utility, many users often complain that they cannot use this utility to scan and repair the corruption in Windows 10. Most of the time, they receive the following error messages when sfc /scannow fails to work.
Case 1. Not Enough Memory Resources Are Available to Process This Command
In fact, the reason causing this issue is that the resource file is not included in the components that are used to keep these copyright strings. When this command tries to read the string, it cannot find the string and provide that the reason is a low-memory condition.
You need to know there is no low-memory condition, and this problem can be ignored because it won’t impact on any features.

This problem usually occurs at the end of this scanning or when sfc /scannow gets struck.
