So what features does Windows 10 Enterprise LTSB add when I would switch to it from 10 Pro ? Except for it fixing the whole "it doesn't crap itself when updating thing" ? Because my Brother might be able to hook me up with a license key once I need one again for when setting up my new Notebook.

I use it on my workstation. More stable updates and overall runtime, from my experience. Much less trouble to manage once you set it up properly. But, could just be bias on my part
