How to make it works

How can make this works WinKill("[CLASS:#32770]")

First, you should be more specific. There are many #32770 class windows on a typical desktop, maybe you are trying to kill the wrong one. Add more info and check that you have the right window first:

$hWnd = WinGetHandle("[CLASS:#32770; TITLE:Your Window Title]")
If (@error = 0) And IsHwnd($hWnd) Then
     WinKill($hWnd)
Else
     MsgBox(16, "Error", "Failed to ID window.")
EndIf

You might also do things like this instead of WinKill():

$hWnd = WinGetHandle("[CLASS:#32770; TITLE:Your Window Title]")
ControlSend($hWnd, "", "", "!{F4}") ; Alt-F4
