Microsoft issued Security Bulletin MS12-004, which is a Critical patch affecting Windows Media - Vulnerabilities in Windows Media Could Allow Remote Code Execution (2636391).
Tonight I was greeted by my Home Server announcing that it had a critical update that just *had* to be installed. I wasn’t happy with clicking the Install Updates button in the Home Network Health dialog so I logged into my Home Server via Remote Desktop and had a look for the Windows Update icon to see what it so urgently needed to install.
