Resolve the local Administrators group name via its built-in SID (works on any language)

$adminSID = New-Object System.Security.Principal.SecurityIdentifier("S-1-5-32-544")

Translate returns "BUILTIN\Administrateurs" or "BUILTIN\Administrators" etc.

icacls only needs the part after the backslash
