System File Checker

To make a long story short, when I contacted Microsoft a few days ago about a problem I’ve been having, one of the possible solutions they gave me was to use the System File Checker tool. When I asked Microsoft’s Virtual Agent about it, she came
back with “…To run it:

• Select Start Windows logo Start button, and in the search box, enter
  Command Prompt. Press and hold (or right-click) Command Prompt (Desktop app) from the search results and select
  Run as administrator.
• Enter DISM.exe /Online /Cleanup-image /Restorehealth (note the spaces before each "/").
• Enter sfc /scannow (note the space between "sfc" and "/").”

After the steps, she provided a link to learn more about the tool (System file check (SFC) Scan and Repair System Files & DISM to fix things SFC cannot).
However, that did not help me much.

Regarding steps 2 and 3, do I have to press “enter” after “…Restorehealth,” or do I type “…Restorehealth sfc /scannow” AND THEN press “enter?”

 

System File Checker scan fails at 24% in Windows 10

Hello to all, and to you, Yashwanth Kotakuri,

My sfc was stopping at 19% and would not continue. I ran DISM as you state above and it fixed everything that was wrong (and there were things wrong). I then ran it again and it gave me 100% and cleaned up all errors.

My question is: If all is well with the DISM and it restored all files, why does my system file checker STILL stop at 19%?

How can I fix the system file checker, if there is one? If DISM says everything is OK, can I ignore the sfc?
