How to install Microsoft Edge browser on Windows 10 Enterprise LTSB
From a ZDNet article:
...the reason Microsoft won't provide Edge to Enterprise users on LTSB is because the company expects to roll out new features and feature updates to Edge on a regular basis... That means it would be kind of pointless to include the evolving Edge browser if it's not going to be updated.
This is further confirmed by recent Google Searches, where responses from MS staff are that the following will not be included in LTSB:
Microsoft Edge, Windows Store client, Cortana (limited search capabilities remain available), Microsoft Mail, Calendar, OneNote, Weather, News, Sports, Money, Photos, Camera, Music, and Clock. Therefore, it’s important to remember that Microsoft has positioned the LTSB model primarily for specialized devices.
LTSB is intended for special scenarios and not for the average desktop, even in a tightly-controlled corporate environment. LTSB is designed for use in Kiosks and other very-special-use systems. The "Long Term" in it's name made lots of big-organization IT groups happy as they thought they'd get some long-term consistency from an OS they could run on their user's computers, but that's not what MS intended this system for.
