Question

my application creates a new instance of winword embedded in a windows form.

new Microsoft.Office.Interop.Word.ApplicationClass()

Once the user finishes editing I close the window but the winword instance is still running in the background.

How can I kill that particular instance? I know how to kill all instances running on a machine but this isn’t an option.

You need to call

application.Quit()

In your code.

One thing I had to do on my system (it’s an excel processing tool) is do a process kill if after the Quit things were still going on.

var openedExcel = System.Diagnostics.Process.GetProcessesByName("EXCEL");
            if (openedExcel.Any())
            {
                foreach (var excel in openedExcel)
                {
                    try { excel.Kill(); }
                    catch { }
                }
            }
