Broken file operation dialogs on Windows 11

[OneCommander Support]

In the recent Windows 11 update Microsoft broke file operation dialogs for 3rd party file managers (Reports from other 3rd party file managers have been showing up in the past days)

Luckily not everyone on Windows 11 is affected, at least not yet. I as the developer can't reproduce it on 3 PCs I have with Windows 11.

Microsoft has not acknowledged breaking anything, so it is not clear if they will fix it and when

 

The options are (for people affected):

Option 1. Download 3.96.2.0 which uses Windows7 file operation dialogs (Microsoft forgot to break those in Windows 11)

Option 2. Keep using Use 3.96.0.0 and:
 2a. Uninstall recent Windows update that broke operation dialogs
 2b. Switch to built-in Taskmaster (or install TeraCopy)

Uninstalling update is not tested and it is not clear what exact update causes this. Microsoft updates are a mess and the same "patch" can be part of different cumulative or other update name for different people. It is also not clear if the patch is permanent, does it patch Explorer or something else, or if it can be reversed at all by uninstalling the update.

Anyone with this issue in OneCommander, please test this little app

https://github.com/m1l/WindowsOperationsBroken/releases/tag/Release

It is minimal example with just one button that copies just duplicates a dummy 3GB file using similar code, and if it causes the same issue I can try sending it to someone at Microsoft

Hi

Yep it does cause the same issue here.

Let me know if you need any more info

from my machine to send to Microsoft.

Thanks for checking! You sent that screenshot of updates in your email, but other than that I can't think of anything else at this moment. 

Please just confirm if you have any:

Windows tweaking apps

Apps replacing Windows taskbar or taskswitcher

Start menu replacements

Window managers

Explorer addons

Window styling tools like windhawk

Mica for everyone or other apps that inject themselves to change other programs' window blur

Anything else that adds additional buttons or overlays to windows

Hi

I've sent you a pm.

In another effort to solve the mystery (and also do the Microsoft's job), I've uploaded a script that when copy-pasted into PowerShell will output a csv file on your desktop with every Windows patch and component installed in the past 60 days, so maybe if we cross-reference this from a few affected users find what it the culprit

PS: Please also upvote this for higher changes that Microsoft fixes it soon https://aka.ms/AAwn4q8

Possible culprit found:

Windows update KB5060842

Anyone with this issue please go to Settings > Windows Update > Update history > Uninstall updates and uninstall KB5060842

[OneCommander Support]

Also caused by KB5063060. Uninstalling that one fixes the issue

Great. Thanks Milos

👉🏻 Just curious, but how does TeraCopy get around this issue?

[OneCommander Support]

TeraCopy doesn't use Windows Explorer dialogs for file operations. OneCommander's Taskmaster also uses the low-level API for file operations and doesn't have that issue. Microsoft "only" broke the Explorer dialogs from showing in other file managers, and that was default in OC, and the first way of doing file operations in V3.

Thanks for the explanation. 👍🏻
