We're 2 to manage IT tasks in the company (my real qualification is software dev though). We don't have access to Microsoft anything (too expensive) so we use the licenses that comes with the computers we (rarely) buy.

I still haven't managed to convert all our workstations from Win 7 to Win 10 (and yes we still have a couple XPs), there are special apps on them that needs the intervention of one of our provider, it's complicated.

Last year one of our provider sent us some machines with LTSB 2016 installed. They're already at their EOL.

Edge is not available and there's not even an image viewer on this OS, MS Photos is impossible to install (and is crap anyway, it regularly fails to show an image that any other viewer including Paint can open etc).

Color me unimpressed.

LTSB (or LTSC) aren't designed for general purpose web office machines. This is one of the reasons it's difficult to get LTSC, it's only available via enterprise and it's designed for a very specific non changing long term environment. It will never have the most updated drivers, or the integration of the latest/greatest web browser or microsoft store.

LTSB is amazing fit for things like kiosks, POS, appliance that are designed for a single purpose only. Uptime & Stability is the purpose, not enduser focus. You should never use it outside of a large enterprise where you can support it.

It is not used on most orgs because LTSB is not meant to be used on desktops, Microsoft docs even say it is not meant for desktops and so they will likely not support you if you use it in a desktop.

LTBS is meant for stuff like ATM or POS as replacement for the older Windows embedded versions.
