That subsequently posted link seemed to have identified the API call, and 
provided some PowerShell-hosted code to call it...

  It's not the shell... I can exit Explorer, and kill the remaining 
EXPLORER.EXE, and I can still toggle the trails on and off using "CONTROL 
MAIN.CPL" (which just starts a RUNDLL32.EXE process).  (Win
7)

  I'm guessing it's done in the GDI or USER layers (or whatever might have 
replaced/supplemented them under NT 6).

  There's presumably an API call or something that occurs to tell 
whatever-it-is to change behavior (or re-read the registry).  ProcMon doesn't 
seem to show anything happening in a quick test; might be my exclude filters 
are too strict.
