It has been confirmed that custom folders are getting a significant change with the June 2026 updates as such folders or folder names defined by desktop.ini will no longer appear after this update is successfully installed. While you may inititally think this is a bug with the new release, Microsoft has stated that this is in fact "expected behaviour" in its new support article regarding this which Neowin spotted today while browsing.

Essentially it's a security hardening measure such that custom folder presentations are treated as potentially unsafe whenever Windows is not sure about their origin and whether that desktop.ini folder can be trusted or not. Here is list of such untrusted files and folders:

• Files downloaded from the internet that carry Mark-of-the-Web (MOTW).
