windows 10 hidden host (marked as system file) fixed.txt

instruction.txt

From a command prompt with administrative access type each of the following commands:

CACLS.EXE C:\WINDOWS\system32\drivers\etc\hosts /G BUILTIN\Users:R
CACLS.EXE C:\WINDOWS\system32\drivers\etc\hosts /E /G "BUILTIN\Power Users:R"
CACLS.EXE C:\WINDOWS\system32\drivers\etc\hosts /E /G BUILTIN\Administrators:F
CACLS.EXE C:\WINDOWS\system32\drivers\etc\hosts /E /G "NT AUTHORITY\SYSTEM:F"
ATTRIB.EXE -S -H +A -R C:\WINDOWS\system32\drivers\etc\hosts

If this doesn't resolve the issue you will need a better program to do it. Download SubInACL from Microsoft. You can work up the syntax for taking ownership or I'll do it if you can't figure it out.

It should be something like:

SubInACL.EXE /file C:\WINDOWS\system32\drivers\etc\hosts /setowner=%USERDOMAIN%\%USERNAME%

then rerun the commands above.
