If you haven’t downloaded KB4034679 and KB4034664 yet, do it as soon as possible. As a quick reminder, Windows 7 facilitated the spread of the Wannacry Ransomware. Keeping your system up to date is one of the main lines of defense against malware attacks.

Have you already downloaded KB4034679 and KB4034664 on your Windows 7 computer? Did you encounter any issues? Let us know in the comments below.

  • These updates caused some display issues with certain programs on our 2nd monitors. When opening / moving Office files or Nuance PDF files to our 2nd monitor, the display would look jagged with screen artifacts. After uninstalling 4034679 and 4034664 the issue went away. This happened for all of our terminal service users that have Wyse thin clients and happened for one person that has a generic brand tower. Has anyone else encountered anything similar?

    • Definitely – KB4034664 is a terrible update – we use a citrix
      environment and it makes the sessions freeze up when dragging the
      program from primary (right) screen to secondary (left) screen. All
      users who have dual-screen setup where the right screen is primary are
      experiencing this issue. Secondary, the follow-up flags in outlook 2010
      disappear when moving outlook to the secondary screen (they reappear
      when moving back to the primary)
