So if I want to opt out Google's WiFi Assistant I have to add


to my SSID.

If I want to opt out from Microsoft's WiFi Sense I have to add


to my SSID.

What if I want to opt out both? Can I combine them?



SSID_nomap _optout?

SSID_optout _nomap?

What a trouble...

Google's _nomap must appear at the end of the SSID while the Windows _optout can be anywhere in the SSID, so this should work based on the docs below:



...you can opt your network out by including _optout somewhere in the Wi-Fi network name (also called the SSID). For example, mynetwork_optout or my_optout_network. When you do this, Windows won’t automatically connect people to your open network.


To opt out, change the SSID (name) of your Wi-Fi access point (your wireless network name) so that it ends with _nomap. For example, if your SSID is 12345, you would change it to 12345_nomap.


You can use SSID_nomap_optout.

  • "The Register seems to think Windows 10 upgraders can avoid each by including both “_nomap” and “_optout” in the Wi-Fi network name, but this article at How-To Geek says users will need to choose the lesser of two evils." So can I combine both or not? Couldn't understand that well. Nov 25, 2015 at 10:07
  • Google and Microsoft opt-out are independent of each other. The register is a horrible source for technology facts, or any facts, for that matter

  • This contradicts the other answer and apparently "Google's _nomap must appear at the end"...?
