Specific command is:
dism /online /cleanup-image /restorehealth
dism /online /cleanup-image /checkhealth
Repair system files, use these two commands.
Operating System: win7

We found no restorehealth and checkhealth related presentations. Introduction scanhealth option are also able to perform normally. So there is no doubt these two options.
Notepad ++ file with the search function, the search of these two options in the following two directories:
C:\Windows\System32\Dism\
C:\Windows\SysWOW64\Dism\
It is not found, but scanhealth to find, located
C:\Windows\System32\Dism\DismCore.dll
It is believed win7 does not support this option, but others say the Internet has this command. Then extracted from the win10 install image DismCore.dll, look for these two commands, found it. Then continue to search for related presentations online, win8 found to have more than two options.
So win7 want this command option to repair the system files is impossible.
