How to re-enable the "Expand to Open Folder" option?

That option is also available in the View menu. I tired that through the menu - option/view/navigation pane when it first started happening but that expands everything. That is worse than than the no expanding when you have hundreds of folders

vt9, you are very correct !

That is why I noticed the solution forwarded by Giovanni O, is not what we are looking for...

Let's hope one day someone will find good solution that works, or even better: a repair by Microsoft (update).

Yes. A fix by Microsoft would be good so that this feature truly works as it once did.

I am quite puzzled because on my pc this solution (copied on KernHardmann and Tjaart Venter posts above) work different from "expand all folders".

if I select the last option, when I open the standard icon of Explorer, on the left panel all the directories expand (at first level) and if I double click one of them the "expand to open folder" works correctly. But I agree that is a mess because you have too much directories opened on left panel. (in short, Desktop, Documents, Downloads, etc all expanded)

If I create the shortcut, when I open Explorer using it the left panel is the standard one (with all the directories closed) and in the right panel I have the target directory chosen. I double click on one of the subdirectories in it and automatically in the left panel only the target directory expand up to the current position starting from My PC, and all the other directories remain collapsed (in short, only the directory C:\Users\Administrator\Documents\Work)

On desktop, right clik, New, Shortcut. Copy this:

C:\Windows\explorer.exe %USERPROFILE%

on the prompt (you can change %USERPROFILE% with any path you prefer, like C:\Users\Giovanni)

the next screen asks for a name of the shortcut. End.

Then you can just drag this new shortcut to the taskbar.

Please note that if you create a shortcut in the standard way (in Explorer, right click on the folder you want to link, Other options, Create shortcut) it does not work

not working as expected for me
