Hello & Thanks ;
WIn 10 vs 2019 

p.Close() not working for me .    
        Private Sub CloseIExplore()  
            Dim processArray As Process() = Process.GetProcessesByName("iexplore")  
            For Each p As Process In processArray  
                p.Close()  
                TextBox1.Text = TextBox1.Text & ControlChars.NewLine & "For Each p As Process"  
            Next  
            TextBox1.Text = TextBox1.Text & ControlChars.NewLine & "Private Sub CloseIExplore()"  
        End Sub

It seems to be running fine , but it doesnt 'End Task' .
Please , what am I doing wrong ?
Is there another way ?
Thanks for your Help...

    Hi Vernon Marsden,
    In your another thread, I have explained in detail that Process.Close() method is used to free all the resources that are associated with this component.
    And you can use Process.Kill() or Process.CloseMainWindow() method to stop the associated process.
    Does this solution work for you? If not, what problem did you encounter? If it is resolved, please click "Accept Answer".
    For the same problem, we suggest discussing on a thread instead of creating a new one.
    Thank you for your understanding.
    Best Regards,
    Daniel Zhang

    Thanks Daniel ;
    I read elsewhere that .p.Close() is best to use because it will not only Close but will allow the process to clean up its ,resources , Close neatly ,
    where as p.Kill() will just kill it and all its resources .
    But I just now tried .p.Kill and it works great .

    I lost track of the other post , thought I had marked you as Answered .
    My apologies .
    Thanks
