Or if you are looking to run the DOS command from C# then you could use

System.Diagnostics.Process.Start("cmd.exe", "REG DELETE HKLM\SOFTWARE\Wow6432Node\WindowsApplication1\Status /f")

This was not worked for me. Just opening command prompt as usual & passing that line of code successfully. But the key is not deleted. – JayNaz Apr 17 '15 at 05:01

Here's one approach. Note that you have to pass true to OpenSubKey in order to get Write permission.

var hklm = Microsoft.Win32.Registry.LocalMachine;
var subkey = hklm.OpenSubKey("Software\\Wow6432Node\\WindowsApplication1", true);
subkey.DeleteSubKey("Status");
