Sure, why not, but windows permissions are much more complicated than that, so if

$ ls -loanh C:\AUTOEXEC.BAT
-rwxrwxrwx  1 0 394 2011-03-24 20:44 C:\AUTOEXEC.BAT
[download]

satisfies, then it satisfies :)

If it doesn't, there is always cacls/Win32::FileSecurity

$ cacls C:\AUTOEXEC.BAT
C:\AUTOEXEC.BAT BUILTIN\Administrators:F
                NT AUTHORITY\SYSTEM:F
                BUILTIN\Administrators:F
                BUILTIN\Users:R
