Here's the solution. If you download the new DCH Thunderbolt drivers for your PC or laptop from Intel, unzip them into a folder. In Device Manager, look in System Devices for something named Thunderbolt Controller. Right click, select "Update driver" then "Browse my PC" and point to the INF subfolder in what you extracted. This will not only update the Thunderbolt driver, it will automatically upgrade you from Thunderbolt Software (the old version) to the Thunderbolt Control Center (the new version). It is in the MS Store, but you can't see if you're running Thunderbolt Software (why it works that way, I have no clue, but I've seen this on all 3 systems I've now upgraded this way).
Interesting thing, this. I'll be blogging about it on edtittel.com tomorrow, in fact...

PS to give credit where it's due I learned this from the second element in this online forum thread: Thunderbolt Control Center vs Intel Thunderbolt Software
