Windows Live Messenger 8.5尝鲜 (Download and Installation)

I believe many people know that there are some leaked versions of Windows Live Messenger 8.5 online (some are even called MSN Messenger 8.5), and these downloads may come bundled with ads and spyware.

The version I found here is the official one with a Microsoft digital signature.

You can check this by looking at the download file's properties > digital signature (as shown below).
