How can I get Edge to restore all the tabs I had open last session?

In this History "Recently closed", it seems that there are 2 types of entries in the list.

1. Individual Page visits
2. Browser Window Instances that have a triangle to the left of their name

(in this screenshot, Edge Windows are yellow-highlighted)

So in my case, after rebooting without closing my 3 Open, and named, Edge windows, on restarting Edge, it only opened 2 of my windows. However I found the 3rd one in this list, and was able to right-click Open in New Window, and there were all my tabs.

A recommendation for Microsoft is that

1. Notice that these Window entries in History List are not retaining the "NAME" of the window I assigned, they are named like one of the tabs. So it makes it hard to recognize and find the previously open window.
2. Consider adding a feature such that whenever a user assigns a NAME to an Edge Window, that Edge persists that name in it's local storage, along with all of the child tabs. Then instead of finding it in History, there could be a place in the UI to maintain your list of Named Edge Windows.

A Name can be assigned by right-click the Edge title bar and choosing "Name window..."

Hi there is no "When Microsoft Edge starts" in my Edge settings

hi, no, the history window is empty, like it's auto deleted it when i last shut down grrrr!
How do i set the program to NOT auto delete AND open my previous tabs when restarting Edge please?

Yeah, this has happened to me enough times I think I'm just done with microsoft edge. Thanks for nothing, edge!!

This is a moronic answer. How is this guy an MVP? Just look at the next answer below, by a volunteer moderator (!) for the correct response. Good lord, Microsoft...
