Is my PRIVACY AT RISK while using windows 10 ???

Not just with windows 10. Windows Phone is the same story

So far as I can see, most of our data is out there somewhere what with MS, Amazon, Google and others. The US intelligence agencies are all tapped into the Internet and the UK agencies are too. Hopes of privacy are a little forlorn unless one gives up- on the Internet and mobile phones. So I can't see much of a deal with Microsoft spending a fortune on servers to process all this data we are sending, voluntarily, to them to allow them to improve Windows 10 to a final product.

As has been said, no one has to do this and no one has to do this on the main machine they use - even Microsoft don't advise this. So put Windows 10 on a separate machine and do your usual things on another machine ans no problem ... apart from the everyone else who gets hold of your data.

Interesting discussion.  If you watched 60 Minutes Sunday night (10/5/14), you saw the head of the FBI say the Chinese already have everybody's info.  He said there were two kinds of people; those who know they've been hacked by the Chinese and those who don't.  

 Fortunately I don't have any accounts with JP Morgan-Chase, but I did use my Visa card at Target and Home Depot.  I haven't used Windows 10 TP to access any financial accounts fortunately, but those who have should change their passwords on something other than Windows 10 and probably use a browser other than IE.

You may "highly doubt" it, but read the actual privacy statement:

"When you acquire, install and use the Program, Microsoft collects information about you, your devices, applications and networks, and your use of those devices, applications and networks. Examples of data we collect include your name, email address, preferences and interests; browsing, search and file history; phone call and SMS data; device configuration and sensor data; and application usage,"

Specifically, Microsoft may collect "voice information" when people use "speech-to-text" features, file information about files that users open, and "typed characters," meaning text that users compose.

There is no differentiating between what "typed characters" are.

Don't get me wrong.  I understand the desire to collect most of this data DURING THE TESTING PHASE, but Microsoft is being really quiet on their plans for the final release version:

 "When we release the new version of Windows, we will have a privacy statement that reflects the final product, and will share more as development continues," a spokeswoman from Microsoft said via email when asked for comment.  (Source)

I really don't understand how or why MS would try to keep this Privacy policy intact for the final release, but if they do, a lot of people, myself included, will likely jump ship for a different O/S.

Only time will tell.  Until then, I run the Tech release on a non-production box that won't have anything "important" entered on it.  Of course, MS won't get the proper feedback they are looking for from me (and hopefully most others), but that's just the way it works.

Need to add NAP-NetworkAccessProtection as there is NONE ,unless it's under another name !!!
