Once upon a time there was a fully functional Windows 7 x64-aware computer, later, dark lord Microsoft released Security update KB2859537 and computer was unable to run most of applications. And system administrator decided to uninstall this update from Control Panel, but couldn't find it in "View installed updates" section of "Programs and features" part, but found it in "View update history" section of "Windows update" part.
Then he decided to download that update and run install/uninstall manually, but...
Package listed in registry, but dism doesn't report it with /online - this update is removed from Windows Updates by Microsoft now: http://pastebin.com/J5QpQXg0
