I'm using Windows 7 Home Premium 64-bit OS.  I have been using Windows Live Mail as my email client for a long time.  The recent update first offered via an email from Microsoft and then pushed as an optional update in Windows Update has caused WLM 2012 to become inoperable.  This news story seems to be about the problem I'm having and is a good indication that I'm not alone:

Unfortunately, when I look at recently installed updates, KB3093594 does not appear on the list, so there doesn't seem to be a way to un-do the installation of it.  How can I get my WLM 2012 working again?
