Did you know that 51% to 60% of government core business applications were implemented between 1990 and 20091 — making them between ten to thirty years old? While government institutions might be the extreme, from my experience I can safely say that financial services, manufacturing, and other legacy system-heavy industries are not lagging much behind.
It is for this reason that some enterprises considered implementing Microsoft's Long-Term Servicing Channel as a convenient escape route from the mandatory Windows-as-a-Service upgrade pace. While an Operating System is certainly not a legacy application, some organizations seem to think so. According to a Dimension Research report, one in five companies with more than 5,000 employees planned to deploy the LTSC in 2017 — that is a massive increase of 27 percent compared to 2016.
(In contrast, according to InfoTech's reporting, LTSC is at MOST 2% of all devices.)
