Windows 11 update crashing ExplorerPathcer

[phpjunkie420]

Windows 11 update KB5027303 is causing ExplorerPatcher to crash.

I believe I'm running into this too. When I log in my desktop is black but I can still see my cursor, launch task manager, run tasks, etc.

Restarting explorer in task manager did not solve the problem

Got the same. Just after today's update. Black screen after log in. I had to uninstall ExplorerPatcher to be working again. If anyone is struggling how to do it, I did it the following way (as appwiz.cpl won't launch on the "black screen account"):

1. cmd
2. net user administrator /active:yes (this will add a new administrator account)
3. log in on the new Administrator account and wait for it to be set up (took pretty long time)
4. uninstall ExplorerPatcher from the Administrator account

However I cannot find the update 5027303 on my machine but rather this one:

Will test with and without updates.

Edit: Uninstalling the update KB5027231 made ExplorerPatcher work again.

But explorer windows and Microsoft Store and random "modern" apps are crashing randomly.

That's a preview update: https://blogs.windows.com/windows-insider/2023/06/20/releasing-windows-11-build-22621-1926-to-the-release-preview-channel/

Uninstall it and don't install preview updates because they do not supply symbols to download: https://github.com/valinet/ExplorerPatcher/wiki/Symbols

After upgrading to 22621.1928 (final) (aka KB5027303) symbols for that build are not being downloaded afterwards … Then, tried to force them to be downloaded by enabling 'Advanced/Enable console' but symbols install fails, too !? ► Your help to solve the issue would be very apreciated

Here the console log:

I have make the win update, no black screen. Now on the BT Symbol right Click will give ExplorerCrash. after 3 Times a white Windows is displayed. Right Click on the START no more Work, same ExplorerCrash... Deinstall of EP and reinstall will not help (administrator user).

Now i have a big problem.

Uninstall the update, and use the Microsoft's Show or Hide Updates Troubleshooter. This is a Microsoft tool that has been deprecated, so you won't find it on any of Microsoft's websites. Microsoft has added something new to the troubleshooter that is built into windows itself. This is the reason the tool is deprecated.

Preview updates and insider builds are not supported due to symbols not being available to download for them: https://github.com/valinet/ExplorerPatcher/wiki/Symbols

[Asphiii]

I confirm that KB5027231 is crashing the app

Steps:

1. Alt+ctrl+delete
2. In task manager run cmd
3. Type: wusa /uninstall /kb:5027231
4. After uninstalling restart the PC

Hope it helps for ya

You can also try the following:

1. uninstall explorer patcher
2. export this registry key: "Computer\HKEY_CURRENT_USER\Software\ExplorerPatcher" and upload it to here
3. delete the same registry key: "Computer\HKEY_CURRENT_USER\Software\ExplorerPatcher"
4. install explorer patcher
5. verify you get a notification that symbols have been downloaded
6. restart windows explorer using either the task manager or in the properties window of explorer patcher

Everything is working fine for me with KB5027303. Symbols downloaded as well.
