When trying to install Windows Updates, you receive the following error:

Code 80243004 – Windows Update encountered an unknown error.


This is a documented issue by Microsoft and has a weird workaround.  Please follow the steps below for updates to continue installing.  Office KB article can be found here: http://support.microsoft.com/kb/2837515

  1. Right click on the taskbar and select Properties.
  2. Click the Customize… button on the Taskbar and Start Menu Properties window.
  3. On the Notification Area Icons window, make sure Always show all icons and notifications on the taskbar is checked and click OK.
  4. At this point, try running Windows Update again and the updates should begin to install properly.

Not sure why this fixes the issue, but it worked for me on a couple of virtual machines running in a VMware environment.  An additional thing I noticed is you can see the tray has “null icons”, where they are blanks of open applications; once you hover over them, they disappear/close.  Not sure if this is a bug with Windows and VMware VMs, but just thought it was a weird coincidence.  If you have had this same issue, could you please drop a comment below stating whether or not you received the same issue in a virtual environment?
