# Live-hive shell-folder repair for a logged-in user whose Documents/Downloads
|
|
# sidebar is showing "this file has no associated app" after a folder-redirection
|
|
# GPO applies only the legacy (Personal) name but not the modern KnownFolder GUID.
|
|
#
|
|
# WHEN TO USE
|
|
# The Folder Redirection CSE has written the UNC path to `Personal` / etc,
|
|
# but the matching GUID value ({FDD39AD0-...} for Documents,
|
|
# {374DE290-...} for Downloads) is still pointing at a local path, so
|
|
# clicking the sidebar item tries to open the local folder and fails.
|
|
#
|
|
# HOW TO RUN
|
|
# ScreenConnect Backstage PowerShell. User SHOULD be logged in so the hive
|
|
# is live. Edit $SID and $UNCBase at the top before running.
