System.Diagnostics.ProcessStartInfo startInfo = new System.Diagnostics.ProcessStartInfo();
startInfo.WindowStyle = System.Diagnostics.ProcessWindowStyle.Hidden;
startInfo.FileName = "cmd.exe";
startInfo.Arguments = "powercfg -setactive  8c5e7fda-e8bf-4a96-9a85-a6e23a8c635c";
process.StartInfo = startInfo;
process.Start();

Solution 1

CMD needs a /c switch to execute a process passed as argument, so you'll have to do this:

C#

startInfo.Arguments = "/c powercfg -setactive 8c5e7fda-e8bf-4a96-9a85-a6e23a8c635c";
