File Explorer's navigation bar doesn't update when navigating shell namespace extension folders
This article describes a problem where File Explorer's navigation bar doesn't update when navigating folders in a shell namespace extension.
After you install KB 5031455 on Windows 11, version 22H2 or Windows 11, version 23H2, File Explorer's navigation bar doesn't update to show the current folder when navigating folders in some shell namespace extensions. Additionally, File Explorer's navigation bar can't be used to navigate folders in the same shell namespace extension.
This issue is fixed in KB5041587.
With a namespace extension, application developers can take any body of data and have Windows Explorer present it to the user as a virtual folder. When a user browses this folder, the application data is presented as a tree-structured hierarchy of folders and files. Users and applications can interact with the contents of this virtual folder in much the same way as with any other namespace object.
