Kill&ReStart the "touch keyboard" before bringing it "up" ( on screen ).

In Win10 Ver 1803, DesktopMode, there is no reliable way to  
toggle the "Touch Keyboard" on|off [ ITipInvocation.Toggle() ];  
nor can you _reliably_ discover if it's "up" ( on screen )  
[ IFrameworkInputPane.Location() ]; both routines fail _randomly_.  

Instead, ensure that "TabTIP.EXE" and "....InputApp.EXE"  
only run when the keyboard is "up" ( on screen ).  

To toggle the keyboard on and off ( from X.CPP in Jeff-Relf.Me/X.ZIP ):  

    if ( WM == WM_HOTKEY && C == 'K' ) {
    
      //  A mouse button takes me here.  Jeff-Relf.Me/g600.PNG
    
      if ( KillProc = 1, Running( L"TabTIP.EXE" ), KillProc = 1, Running( 
          L"WindowsInternal.ComposableShell.Experiences.TextInput.InputApp.EXE"
      ) )  

        //  The keyboard was _On_ ( i.e. its processes were running ), 
        //  so it was "turned _Off_" (killed); and we're done.

        goto Done ;
    
      //  The keyboard was _Off_ ( i.e. no running processes ). 
      //  Turn it _On_: 
    
      Launch( L"%CommonProgramFiles%/microsoft shared/ink/TabTIP.EXE" );
      Sleep(99);

      static const GUID CLSID_UIHostNoLaunch = {  0x4CE576FA, 0x83DC,
        0x4f88,  0x95, 0x1C, 0x9D, 0x07, 0x82, 0xB4, 0xE3, 0x76 };
      static const GUID IID_ITipInvocation = {  0x37c994e7, 0x432b,
        0x4834, 0xa2, 0xf7, 0xdc, 0xe1, 0xf1, 0x3b, 0x83, 0x4b };
      static struct ITipInvocation : IUnknown {  virtual HRESULT 
        STDMETHODCALLTYPE  Toggle( HWND wnd ) = 0 ;  }  * Tog ;
    
      Tog = 0, CoCreateInstance( CLSID_UIHostNoLaunch, 0, CLSCTX_INPROC_HANDLER
        | CLSCTX_LOCAL_SERVER, IID_ITipInvocation, (void**) & Tog );
    
      //  Firefox and Chrome need this: 
    
      Tog ? Tog->Toggle( GetDesktopWindow() ), Tog->Release() : 0 ;    }

      PROCESSENTRY32  aPID = { sizeof aPID };
      PIDs = CreateToolhelp32Snapshot( TH32CS_SNAPPROCESS, 0 );
      Process32First( PIDs, &aPID );
      while ( Found = !strCmpI( aPID.szExeFile, EXE ),
        KillProc && Found && ( 
          aProc = OpenProcess( PROCESS_TERMINATE, 0, aPID.th32ProcessID ),
          aProc ? TerminateProcess( aProc, 9 ), CloseHandle( aProc ) : 0 ),
        !Found && Process32Next( PIDs, &aPID ) );
      
      KillProc = 0, CloseHandle( PIDs );  return  Found ;   }
    
    
    Launch( wchar * Cmd ) {  wchar _Cmd[333];  static PROCESS_INFORMATION Stat ;
      static STARTUPINFO SU = { sizeof SU };
      SetEnvironmentVariable( L"__compat_layer", L"RunAsInvoker" );
      ExpandEnvironmentStrings( Cmd, _Cmd, 333 ), Cmd = _Cmd ;
      if ( CreateProcess( 0, Cmd, 0,0,1,0,0,0, &SU , &Stat ) )
        CloseHandle( Stat.hProcess ), CloseHandle( Stat.hThread );  }
    
    //  CoInitialize(0);
