Windows Edge (browser) won't stay open
This afternoon Edge suddenly stopped staying open. i.e. I click on the Edge icon and an Edge window opens but closes silently about 5 seconds later. Edge worked fine earlier in the day and the only things that I did besides e-mail (Thunderbird) and browsing (Vivaldi and Edge) was (a) turn on Clipboard History, (b) turn off the background image on the Windows Log-on screen, and (c) use Windows Sandbox. I reverted (a) & (b) to previous settings, and I don't see how (c) would interfere, much less now how to undo anything the Sandbox might have done.
Next, I went to https://support.microsoft.com/en-us/...ge-not-working:Repair or reset Microsoft Edge
Repairing the browser won't affect anything, but resetting will remove your history, cookies, and any settings you might have changed. To find these options, select the Start button, then select Settings > Apps > Apps & features > Microsoft Edge > Advanced options.
I did both a repair and a reset.
Next, I did Reset Microsoft Edge to Default in Windows 10
Then, I did Reinstall and Re-register Microsoft Edge in Windows 10
Is my only remaining option to do a Windows Repair from installation media? I have an .ISO file for Windows 10 v.1903 that I used to fresh install Windows. If I use that to do a Windows Repair, will it wipe out all the Windows Updates that have been done and/or will it reset any/all Windows tweaks I have made?
