Hi,

>> But in some machine, the keyboard always not open, Why?

You can also try TabTip.exe

  string progFiles = @"C:\Program Files\Common Files\Microsoft Shared\ink";
             string keyboardPath = System.IO.Path.Combine(progFiles, "TabTip.exe");
             System.Diagnostics.Process.Start(keyboardPath);

If these is not working because some reasons, I recommend you use custom keyboard, you can integrate the keyboard  in to your WPF Application directly.

As far as I know, Soft Keyboard Support add in .NET Framework 4.6.2 , Soft Keyboard support enables automatic invocation and dismissal of the touch keyboard in WPF applications without disabling WPF stylus/touch support on Windows 10.

See: https://blogs.msdn.microsoft.com/dotnet/2016/08/02/announcing-net-framework-4-6-2/

TWO points you must note.

1. Install NET Framework 4.6.2 or later.

2. OS must be Windows 10 Anniversary  or later.
