Uhuh… W2K12 (Windows Server Standard 2012) was released on 10/30/2012. Mainstream support lasts until 10/9/2018… that’s just shy of 6 years! Extended support lasts until 10/10/2013. Updating the OS is a couple of clicks every month and a reboot.
Kudos to Lucee for the easy updates in . versions, but going from 4.5 to 5 isn’t so simple.
