Detect if Java application was run as a Windows admin

Question

I have a Java application. Is there anyway I can tell if the process was run with admin privileges, on Windows 7.

Answer 1

I found this code snippet online, that I think will do the job for you.

public static boolean isAdmin() {
    String groups[] = (new com.sun.security.auth.module.NTSystem()).getGroupIDs();
    for (String group : groups) {
        if (group.equals("S-1-5-32-544"))
            return true;
    }
    return false;
}

It ONLY works on windows, and comes built in to the core Java package. I just tested this code and it does work. It surprised me, but it does.

The SID S-1-5-32-544 is the id of the Administrator group in the Windows operating system.

Here is the link for more details of how it works.
