This morning, I noticed that a new Windows update was offered to me. It looks very suspicious to me:



Here are the update details:

Obviously, this seems way too fishy to install, but I would like to know more. Has everyone received this update (Google only has a couple of hits for this)? Could this be an attack? Is there a way to download the update data without installing it?

I'm open to any ideas.

I'm running an Windows 7 Pro (64-bit).

As @Buck pointed out below, the update is no longer available through Windows Update. I'm not sure how this question will be resolved.

The official communication from Microsoft at this time: 


  “We incorrectly published a test update and are in the process of removing it.“ – a Microsoft spokesperson


I won't add commentary, but will update the answer as more information becomes available.
