Gartner analysts revealed this week that Microsoft's new Edge browser will not be available on the Long Term Servicing Branch (LTSB) of Windows 10 Enterprise, and this has been confirmed by Microsoft's representatives elsewhere.
LTSB is a highly specialized version of Windows 10 that will only be sold direct to enterprise customers. The concept of LTSB is that it is used in locked down scenarios where the client wants as little change or disruption as possible.
LTSB PCs only receive security patches and urgent hot-fixes but no new features for 10 years. This is to minimize the potential for disruption. Microsoft has confirmed this finding.
Browsers tend to be attack targets. Microsoft has rolled out Internet Explorer fixes almost as often as Windows fixes. And Edge is new, so I'm betting it will see a pretty good share of fixes, especially in its first year. So the strategy is to keep a soft target like a browser out of such a sensitive OS platform as LTSB.
Michael Silver, the Gartner analyst who first broke the news, also speculated that over time, apps may not work on LTSB. He argued that as other versions of Windows 10 are updated with new features, apps are likely to evolve to take advantage of those new capabilities. LTSB PCs will be locked on to the original version of the OS, so new features, like .Net upgrades and apps that use them, may not work on those LTSB systems.
Windows 10 will be commercially available on July 29, as the pop-up window on your computer has undoubtedly told you countless times. However, there is no launch date set as yet for Windows 10 Enterprise. Directions on Microsoft analyst Wes Miller speculated it would be Oct. 1.
