I have been having problems when I go to install the above update. I click 'restart' to allow the computer to update but it never does. The dock and desktop wallpaper remain but the menu bar at the top and all icons on the desktop disappear.
I have the same problem exactly whenever I go to shut down the computer. I click shut down and again the dock and background stay but everything else vanishes. It is as if it has only partially gone through the process.
Any help would be greatly appreciated.

Your problem is in no way related to
Security Update 2016-001.When your Mac want to terminate a system update, it should go through a normal
Restart...as the one you see in > Restart.... And to achieve this restart it must terminate correctly all the processes actually running.Your actual problem is caused by one process which refuse to exit correctly.
The first and easiest way to diagnose which process is the culprit consists of using the combination to force quit any ill behaving application:
command ⌘option ⌥esc
If my hypothesis is correct you might see a typical application flagged as
not responding. This mean that this process became deaf stupid and won't hear the signal sent by the system to tell it to exit. In this case, just kill it with the Force Quit button.
