Question

why The process still on Windows Task list manager after close programme ?

i use login Form.cs

 [STAThread]

Answer 1

Because Login is the last form of the application to close, you load Main_User only after that - even if Login is hidden it's still actually there. Windows Forms applications are by default configured to exit when the last form closes.
