Right now, if you have windows spread out across multiple virtual desktops and update (or apply a flag or something) it relaunches them on only one desktop. This is very messy and makes updating a nightmare. Microsoft has control over both Windows 10 and Edge so I think this issue can actually be resolved.
1. not sure how to answer this. I think I explained it thoroughly in my post but I'll provide instructions on how to repro below 2. I'm a general audience user. 3. It's not a specific flag or update that causes this behaviour. It's just something that happens anytime the browser is restarted and you do a session restore.
It's super easy to reproduce.
Step 1: Open Edge (or another Chromium based browser). Navigate to a page.
Step 2: Open a new window and navigate to another page.
Step 3: Open another window and another page.
Step 4: Go to the Windows 10 task view and drag each window to the "New desktop" button. Leave one window on your current desktop.
Step 5: Go back to that window and open a new tab and type in chrome://restart (it'll redirect to edge://restart) and then it'll automatically restore your session but open all 3 windows in the same virtual desktop.
I know how to answer 1 now. I hope that this can be fixed by relaunching windows on the same virtual desktop that they were in before Edge is restarted.
My issues with this remind me of Office 365 and how opening a Word (for example) window when another Word window was already open in another virtual desktop would switch to that virtual desktop and open it there. This doesn't happen anymore thankfully and upon a quick search, that issue started in 2015 (i refuse to believe that was five years ago). ngl, I still really miss the old task view from 1709. It's been a while and yet the performance and reliability of the rewritten one isn't on par with the old one although the rewritten touch keyboard did improve. Nowadays, it feels like Windows 10 is in some state where it just gets security patches and nothing else.
oops got super sidetracked there. were you or anyone else over there able to reproduce this? :)
