EDIT (August 5, 2016): This post is now obsolete: the “Anniversary update” or version 1607 allows you to individually enable and disable the quick actions, including Bluetooth. Worth noting: Windows now does not even allow the icon on my PC, perhaps recognizing that it is not even present.
EDIT (June 16, 2016): It’s gone again, because I installed the latest cumulative update for Windows 10. Will keep observing.
EDIT (May 8, 2016): This no longer works for me.
In Windows 10, the Action Center contains some “quick action” tiles at the bottom of its flyout panel. One of the common ones is Bluetooth, even if the PC doesn’t support it. This is evidently frustrating to many people.
I found what I think is the answer:
I know it’s an old joke about Windows that you restart it to get it to work, but I’ve noticed that the unwanted icon shows up whenever I’ve installed a cumulative update from Windows Update… and disappears at the first restart afterwards.
In Windows 10, the Action Center is a flyout panel with information and common (supposedly) actions that you get by clicking the little message icon in the notification area at the lower right of your screen (lower left if you have an RTL language). A sales-language infused explanation is here on Microsoft’s site for Windows (10).
Down in the lower part of the flyout is a collection of “quick actions” – buttons you can hit to bring up common tools like PC Settings and OneNote. One of the common actions is VPN. Evidently Microsoft is expecting them to become a big thing, but my question is:
What is that swirly icon supposed to be? It looks sortof like the Command key on a Macintosh, or maybe this flag from New Zealand. Nothing about it says “virtual private network” to me, nor would I guess that’s what it meant if it was spotted alone in the user interface somewhere.
