Why taking ownership at all?

You made couple of bugs here.
The problem with invalid "Files" here is simply related to the blank space in "Program Files". You should enclose the file name in this directory in "". But don't do it, just yet, first fix another bug (but both problems are good to understand).
The second bug is: you absolutely don't need "cmd.exe". Who told you it should be there? This is just yet another program, a command interpreter, it does nothing special compared to your, as the starting of the process is concerned. In other words, you need only the application file "takeown".
Do this:
string fileName = //...
string application = "takeown";
string arguments = string.Format(@"/f ""{0}""", fileName); // note "" around file name
System.Diagnostics.Process.Start(application, arguments);
Now, about running as administrator. You should better request elevated privileges for the application running this code. You can do it with the application manifest. I explain this problem in detain via references in my recent answer:
Get rights for my WPF application[^].
That's all you need to resolve your problem. By the way, I doubt making ownership of the file like the one you show makes sense. Why? Just a note not related to your question itself.

Not related to your original question much, so I answered in a separate answer. Please combine the code with the one in this solution -- it's clear enough.

[Answering a different question asked in comments: how to run a console application with the console hidden:]
This is simple:
System.Diagnostics.ProcessStartInfo startInfo = new System.Diagnostics.ProcessStartInfo();     
startInfo.FileName = application; // I refer to the code I've shown in my Solution 2
startInfo.Arguments == arguments; // here, too
startInfo.WindowStyle = System.Diagnostics.ProcessWindowStyle.Hidden; // this solves this problem

i wanna help from you ,i used this code it work fine for program files directory but not working for windows directory.
Sergey Alexandrovich Kryukov at 5-Oct-12 15:45pm
This is unrelated issue, but could be related to access to files or something like that.
Fist, try to run the application manually with the code line to make sure it works with the permissions you have. If not, try to run as administrator and compare:
Check up the path names, make sure the path names with blank spaces are in ""...
