Hello
I understand your frustration with the issue of local_%username% folders not being cleared on exit. This seems to be a known issue with FSLogix and has been reported by multiple users.
The problem typically occurs when FSLogix tries to delete the local_<username> folder but can’t because there are files in that folder that are still in use. This prevents the deletion operation for the local_<username> folder from succeeding.
As for when this issue will be resolved, it’s hard to say. Microsoft has not provided a specific timeline for the resolution of this issue. It’s recommended to open a support ticket with Microsoft to get personalized assistance for your specific environment.
