windows 10 privacy issue

As windows was launched on  29 July 2015 ,even 14 millions devices installed windows 10 within 24 hour from the launch .

But many of the users are complaining about the privacy issue.

privacy issues are as follows :-

1.windows can access online activity .

2.windows can access and share WiFi password .

3.windows can access your folders .  

Solutions to above problem :-

1. turn off WiFi sharing that WiFi Sense 

go to settings then click on network then WiFi sense 

then uptick the option connect to networks shared with them 

2.For privacy go to settings then click on privacy then uptick  option which seems irrelevant

3.If  you are really concerned about the privacy then don't login with your Microsoft account  .
