Don't know what you are talking about. I can't reorder multiple windows of a same program, after unlocking taskbar and restart! Also there is problem of persistence, I can have easily 10ths of windows, I need for it to remember order, even after Firefox is restarted! Problem is program makers...
How did you make it work? It doesn't remember order, after relaunch of browser!
Isn't it. Honestly if I installed 3rd party utility every time I need something... But Microsoft is too busy installing bloatware, spyware on out computers and making money... Why would they fix bugs, or include...
