My previous reply was missing "takeown" to take ownership. The correct sequence of commands is:

icacls config /t /q /c /reset
icacls config /inheritance:d
takeown /f config
icacls config /remove:g "Authenticated Users"
icacls config /remove:g "Users"
icacls config /remove:g "Everyone"
icacls config /grant "%USERNAME%:rw"

This is equivalent to "chmod 600 config".
