How can I check using C# if my process is running as the local Administrator?

I know how to find out if the current user is a member of the builtin Administrators group. But this is not what I want to know. I want to know if the current user is the (one-and-only) special local Administrator account.

I do also know how to retrieve the name of the current user, but I do not want to compare that to the hardcoded name "Administrator" because this will not work with localized versions of Windows (e. g. "Administrador" in Spanish, "Administrateur" in French etc.).

Answer 1

this is the way i use

    WindowsIdentity user = WindowsIdentity.GetCurrent();
    WindowsPrincipal principal = new WindowsPrincipal(user);
    bool isAdmin = principal.IsInRole(WindowsBuiltInRole.Administrator);
