Actually the problem is that if I already have IE instance then newly created instance have no window handler. It is the child instance of the already opened IE instance.It has no hWnd. So my problem is that If i don't have child instance's hwndhow do i can close that one.

you can use Windows API ShowWindow or ShowWindowAsync function [DllImport(user32.dll)] public static extern int ShowWindow(int hwnd int ncmd); public static void MinimizeWindow(Process process) { try { ShowWindow(process.MainWindowHandle.ToInt32() 2); } catch (Exception e) { //log exception } } Check this link: https://social.msdn.microsoft.com/Forums/vstudio/en-US/9bde4870-1599-4958-9ab4-902fa98ba53a/how-do-i-maximizeminimize-applications-programmatically-in-c?forum=csharpgeneral
