Officially, LTSC is a specialized edition of Windows 10 Enterprise that promises the longest intervals between feature upgrades of any version of the OS. These customers, Wilcox said, were "looking to unwind their LTSC deployments and shift to SAC," referring to the twice-a-year Semi-annual Channel release rhythm as he described the second-guessing. He also recounted instances when he had worked with customers who had adopted LTSC (dubbed LTSB at the time, for "Long-term Servicing Branch") at Windows 10's mid-2015 release. Įlsewhere in his epistle, Wilcox spelled out Microsoft's position on LTSC's suitability (MRI imaging equipment, air traffic control devices and others), its cadence (every three years or so) and omissions (no Edge, no Cortana). "All too often, I have seen strategic decisions about Windows 10 servicing options and the use of the Long-Term Servicing Channel driven by the wrong criteria, for example, IT professional familiarity prevailing over end user value and impact," John Wilcox, a Windows-as-a-Service (WaaS) evangelist for Microsoft, complained in a post to company blog last week. Microsoft has again disparaged Windows 10 Long-term Servicing Channel (LTSC), the OS feature-fixed version that most resembles the now-discarded traditional Windows maintenance model.
