Thanks for all of the tips guys!
 
It has settled down now that it's "caught up" and I have Wi-Fi set to "Metered".  My plan is to periodically plug it into wired network to let it do its thing.
 
If this was a production laptop, I would go with Pro and be done with it.  As this is more/less a replacement for my previous Big Chair tablet, workflow interruptions aren't critical.
 
Thanks for the tip about Hotspots ... that will be Step 1 when I'm on the road, which is thankfully not that often these days.
 
I'll haunt Tenforums and other places until I have this figured out ... I am sooooo glad I ignored the FREE Win10 upgrades on my 8.1 DAW.  When it gets replaced it will be 10 Pro for sure.
 
I do wish I could get rid of the Windows Firewall nag.  I have Win Firewall off because I'm behind a hardware firewall.  I'm able to turn the nag off permanently in 8.1.  I wonder how much longer it will be before we lose all control of our machine settings.
 

I have a "hardware" firewall with my router, but I still keep the Windows firewall on.  Does not hurt anything either with Sonar, or Latency Mon.   But, I disable the NIC when I use Sonar, to prevent any potential problem.

Glad to hear you got it sorted out Bob!  No need to plug into a wired network.  Just check into Settings > Update & Security from time to time.  It will tell you if there are available updates that cannot be downloaded due to the metered connection.  Just click ok to download and temporarily bypass the restriction.  Easy!
 
Edit: You may need to click "Check for updates" before you see any updates available to download.  Just did this earlier today.  Works great!

You can turn off individual security and maintenance nags, such as the Firewall.  Control Panel\All Control Panel Items\Security and Maintenance\Change Security and Maintenance settings > Turn messages on or off.
 
Easy if you know where to look
