This relates to opening browser windows in multiple desktops. If one used IE as the default browser, it could be opened in the usual, expected way in each desktop. However, Edge would not. One had to go through a whole rather ridiculous process to put another Edge window in another desktop. Not any more!! One can now open a new Edge in another desktop in the usual, expected way... right @ that desktop... the whole silly ritual necessary of the past is, YAY!!, now, actually, (happily) in the past.

What a welcome sight this is!!
