This is what I've found when I've been experimenting.
NOT A SOLUTION
Tested with:
Win11_24H2_English_x64.iso
Windows11_InsiderPreview_Client_x64_en-us_27774.iso
Note:
The problem occurs in Win11 22H2 any time a *later* package than KB5031354 (22621.2428) is installed.
Every version of Windows 11 23H2 or Windows 11 24H2 has the problem.
This includes the latest (as of now) June 2025 update 26100.4351
Tested on Insider Preview 27774.1000
The problem seems to be present on any version of the updated File Explorer using WinUI.
Assuming a clean, up-to-date install is used in all cases.
No software added other than via Windows Update.
Test
====
- In File Manager, click ... , Options, View, Select "Expand to open folder" and "Show all folders" then Apply
- Create a Folder on C: drive (eg. C:\Test)
- Right-click on the directory and "Pin to Start"
- Click on the shortcut to C:\Test in the Start menu
- The Title Bar indicates "> This PC > Local Disk (C:) > Test". The Left Pane has "Desktop" highlighted and C:\Test is not expanded (incorrect behavior)
Now the weird bit.
- Create a subdirectory under C:\Test (eg. C:\Test\New Folder)
- Click on the shortcut to C:\Test in the Start menu
- File Manager now opens and expands to C:\Test (correct behavior)
Conclusion
==========
I don't suggest adding a subdirectory to every folder you use, that's ridiculous.
Maybe a bug in the way that the folders are addressed, a missing '' at the end of the folder call function?
I've seen the Open File dialog have the same issue and when working with a lot of files it becomes frustrating, CTRL-SHIFT-E aside.
After so long (18+ months) a fix by Microsoft seems to be becoming less and less likely.
