Scroll to edit 2 for an additional flaw. "We will access, disclose and preserve personal data, including your content (such as the content of your emails, other private communications or files in private folders), when we have a good faith belief that doing so is necessary to." Wait what!?!?!? I suppose it's time to send a whole bunch of emails of my junk so Microsoft can store it incase my dong is a threat to national security [spoiler]it is ;)[/spoiler]. Don't worry flood. I have your back. Here is how to opt out of Microsoft collecting data and storing it as they see fit. You'll want to go to setting and privacy which can allow you to disable/enable anything you do or do not want Microsoft to gather. Also cortana plays with your data very loosely. I'd disable her for the time being. There is also one more thing you gotta do. Open the edge browser and in it and set both “Personalised ads in this browser” and “Personalised ads wherever I use my Microsoft account” to off. This will disable Microsoft’s Google-style ad tracking features. Hopefully this helps. Edit 1: added a link Edit 2: [quote]If you're taking up Microsoft on its offer of a free upgrade to Windows 10, you should know that the new operating system has a feature, called Wi-Fi Sense, that automatically shares your Wi-Fi passwords with others. When Wi-Fi Sense is enabled, anyone you have in your Skype, Outlook or Hotmail contacts lists — and any of your Facebook friends — can be granted access to your Wi-Fi network as long as they're within range. Microsoft added this feature to save users' time and hassle, but as independent security blogger Brian Krebs put it, some security experts see it as "a disaster waiting to happen."[/quote] How to stop Wi-Fi Sense sharing If you want to disable Wi-Fi Sense on your computer and wipe its memory, that's not difficult. Go to Settings, select "Network & Internet" and then click on "Wi-Fi." Select "Manage Wi-Fi Settings," scroll to the Wi-Fi Sense section, and turn off each and every feature. But that won't stop people who already have access to your network from sharing that access with others. You could just change your network password, but as soon as you share that password with anyone else, the problem starts all over again. Microsoft offers a permanent solution to this problem, but it's somewhat insane. You have to change your wireless network's name, or SSID, so that it ends with the characters "_optout". So if it's called "joe-network", it'll have to be adjusted to "joe-network_optout". There's another way to avoid this: Buy a wireless router that allows the creation of a guest network that has Internet access, but no access to other devices on the network. Many high-end routers already have this feature. Set up a guest network with an easy password, or no password at all, and sleep easy.
