The old kiosk kept relaunching the dead URL from an HKLM Run value the 32-bit
Inno installer wrote - WOW64-redirected into SOFTWARE\Wow6432Node, which 64-bit
tooling (and the earlier purge) never saw. Broaden the sweep to both registry
views, every loaded user hive, Run/RunOnce/Policies-Explorer-Run, matching by
legacy name AND by any value pointing at the old URLs, plus every per-user and
common Startup folder.
