I have just tried the following and it works fine;

VB

Public Class Form1
    Private OSK As System.Diagnostics.Process
Private Sub ButtonShowOSK_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles ButtonShowOSK.Click
        'Create the OSK Process
    OSK = System.Diagnostics.Process.Start("osk.exe")
End Sub

Private Sub ButtonKillOSK_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles ButtonKillOSK.Click
    Try
        OSK.Kill()
    Catch ex As Exception
        Debug.WriteLine(ex.Message)
    End Try
End Sub
End Class

Note1: the OSK process has a CloseMainWindow() method, however, it returns true, indicating success, but the OSK remains running.

Note2: the OSK process has a Close() method, but nothing hapens.

So, the KILL method works!
