   That didn't work because the command isn't exposed on my Windows 10 system.   
      
   This "concept" is probably the best we can do without going to 3rd-party   
   tools, where just retriggering doesn't work because it's the same cache.

   The "best" so far that I've found that seems to get a "fuller" output is   
   this script which disassociates & reassociates & then scans thereafter.   
      
   It expressly runs a disconnect and scan, a reconnect and scan, and a   
   delayed snapshot and scan because Windows often caches results differently   
   depending on association state.   
      
   But sometimes it leaves the WI-FI adapter in the off state, so I need to   
   add some kind of protection code to make sure the adapter is online.   
      
   If we're willing to run with elevated privileges, we could force a full   
   adapter reset before scanning, but even then we could miss some APs.
