Opening Microsoft Edge Causes Explorer.exe to Hang then Crash

Maybe Tab Session master edge extension: https://microsoftedge.microsoft.com/...glgkikcomfanho
Can somehow help you? I use it for saving my tabs. (I have the same habit with you guys).
I'm also thinking that maybe this started happening since I use edge vertical tabs feature. Though maybe it occurs because since using vertical tabs I have doubled my open tabs.
Your registry tweak seems to have solved my issue!
Thank you.

It did not! I'm investigating it further. To me, the problem appears on startup, when I firstly launch edge browser. If I don't have task manager on, I just log out from windows, then log back in. The issue usually does not reappear until I reboot or shut down PC and boot again.
Thanks again!

So I forgot that this issue existed then I started using edge again and all was fine till about a couple weeks ago when this problem started occurring again.


The only think I noticed (besides the glaring problem with edge) is the in task manager if I click the drop down menu for the Microsoft Edge process there was a "Windows Command Processor" process running (as opposed to there being an independent process). Could this be part of the issue?

I also noticed that while the issue did not occur immediately when I started using edge once it did start occurring it got progressively worse and worse, happening faster and faster each time I opened edge up.

thanks for the tip about the Tab Session Master, I use the search and backup and it can count the tabs.
The only thing I miss is the deduplication feature.

But I have found another extension called Prevent Duplicate Tabs
I had to tune the settings a little so it closes duplicated tabs in different windows and some other which will not consider tabs with link to different paragraphs duplicates.
I did a backup with the Tab Session Master yesterday and there was around 1100 tabs, then installed the Prevent Duplicate Tabs extension and now I see in the Tab Session Master that there is just half of them, and the GDI objects halved as well.

It looks like these two extensions stay in my browser forever :)

Have a nice weekend!

Hi,

I have the same problem as you and I found a solution that works for me. I signed up to share it with you.
The solution is very simple!

Disabling the flag:
edge://flags/#edge-window-tab-manager

Hi,
Don't know what exactly, but these settings solved issue for me:
[CODE][HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\Advanced]
"MultiTaskingAltTabFilter"=dword:00000003
"ExtendedUIHoverTime"=dword:00196608.

Thank you Skyre, that worked for me! I figured it might be a plugin, but Edge kept crashing. I did use 'Tabs Outliner' to replace vertical tabs, but it was 'not the same' - your solution worked instantly.

So, for future reference, I created this .reg file (copy code below, paste it in .txt file and change the extension to .reg)

Does this reg key still work after the latest Edge 118 update in 22h2? Edge has removed the flag edge://flags/#edge-window-tab-manager
so the solution to the problem I had before had stopped working and I am now looking for another solution. If any one can confirm this it would be very helpful.

Just tested the registry and it did not work for me. The behavior of Edge needs to be modified, the operating system is fine.

Yup, doesn't work in 118 - I reverted back to 117 (a pain in itself, as you can't uninstall Edge via Installed Programs).

So:
1: Rip out 118 here: C:\Program Files (x86)\Microsoft\Edge\Application\118.0.2088.46\Installer (keep any 117 folders)
2: Run some Regcleaner
3: In this folder (or similar) there is a .7Z-file: 'MSEDGE.PACKED.7Z (unzip - 7-ZIP is free)

4: Then unzip the .7Z file within
5: It contains the complete Edge folder (with subfolders)
6: Move that to: C:\Program Files (x86)\Microsoft\Edge\Application\117.0.2045.60
Like so:

7: In that folder: msedge.exe
8: Run the .reg file (see above)
9: Open Edge and then disable: edge://flags/#edge-window-tab-manager

Edge was my default browser, but I made another one (Vivaldi) default (just in case 117 updates (something...) and freezes everything again...).
Updating in 117 doesn't seem to work anymore ('there is a new version'), but for now I don't care - I will check next month or so (manually) as I'm not going to waste more time on this MS crap. We'll see, as obviously, you never know what they mess up next time...

Old solution from here seems work with new Edge version.

Flag:
edge://flags/#edge-window-tab-manager is back on Edge version 120.
