Process.Kill() returns access denied

I'm trying to kill a process using a CMD command line from my C# application but when i start the application nothing happens... When i try to kill from command prompt i recieve the message: "Access denied". I've tried to run my app as Administrator and the process was killed. How can i manage not to always use "Run as Administrator"?

Code:

System.Diagnostics.Process process = new System.Diagnostics.Process();
            System.Diagnostics.ProcessStartInfo startInfo = new System.Diagnostics.ProcessStartInfo();
            startInfo.WindowStyle = System.Diagnostics.ProcessWindowStyle.Hidden;
            startInfo.FileName = "cmd.exe";
            startInfo.Arguments = "/C taskkill /F /IM APP.EXE";
            process.StartInfo = startInfo;
            process.Start();

It's means that your application was ran under administrator, so you can kill it only under administrator too. Try too launch application under another user.

Hope this help.

Try this

System.Diagnostics.Process process = new System.Diagnostics.Process();
        System.Diagnostics.ProcessStartInfo startInfo = new System.Diagnostics.ProcessStartInfo();
        startInfo.WindowStyle = System.Diagnostics.ProcessWindowStyle.Hidden;
        startInfo.FileName = "cmd.exe";
        startInfo.UserName = "Administrator";
        startInfo.Password = <password>;
        startInfo.Arguments = "/C taskkill /F /IM APP.EXE";
        process.StartInfo = startInfo;
        process.Start();

You need to set this in the manifest

<requestedExecutionLevel level="requireAdministrator" uiAccess="true"/>
