Question

I have a java program, which will run on windows, which I want to run differently, based on if the program is run with administrative privileges, versus if the program is run as a normal user.

I need a solution that is general, which can work for different flavors of java (not just oracle/sun’s version).

Answer 1

I used the reg query approach to determine if the current program is admin access or not. The following should give enough info that you can modify it for your needs.

    try {
        String command = "reg query \"HKU\\S-1-5-19\"";
        Process p = Runtime.getRuntime().exec(command);
        p.waitFor();                            // Wait for for command to finish
        int exitValue = p.exitValue();          // If exit value 0, then admin user.

        if (0 == exitValue) {
            System.out.println("admin user");
        } else {
            System.out.println("non admin user");
        }

    } catch (Exception e) {
        e.printStackTrace();
    }
