using psexec with cmdkey to store credentials is not working with latest psexec

Question

I am using psexec -s cmdkey to store user credentials. This was working with 1.94 version of psexec and is not working with the latest version 2.34.

I want to know what are the new changes in the psexec? It looks like security related. Here is how it is invoked in my app..
Process procesCred = new Process();
procesCred.StartInfo.WindowStyle = ProcessWindowStyle.Hidden;
procesCred.StartInfo.FileName = "cmd.exe";
procesCred.StartInfo.Arguments = CommandLineutil; //psexec .......
procesCred.StartInfo.WorkingDirectory = psexecPath;
procesCred.Start();
