Stop Microsoft 2012 Server from Rebooting after Update (T minus 15 and counting)

You would think that "Shutdown -a" would stop the count down for a 2012 Server from rebooting on you while logged in, but you would be wrong.  You will simply get a message that says, Unable to abort the system shutdown because no shutdown was in progress. (1116), even though you just saw the prompt that it would reboot in less than 15 minutes.  

I have read that simply stopping the windows update service with "NET STOP WUAUSERV" would do the trick... but that doesn't work either. The count down timer is still running. 

The only way that I can find is to keep the server 'locked' until such time as you have set aside for it to reboot, then log back in to it, and allow the reboot.  To lock the server remotely, through remote desktop, do CNTRL+ ALT + END, this will prompt you with a command menu with the option to LOCK the screen.  

According to Microsoft, this is your only default.  However there is an option available now. Article details how to enable an older way of installing updates, which gives you a bit greater control of when an update is applied and the server reboots.  

I do think that Microsoft should allow System Admin's a bit more control by default.  The server OS should assume that it is being supported by a qualified admin, and not a desktop user.  There are many applications that we need to visually verify are working properly through remote desktop, and not necessarily accessed just through RSAT.
