A simple trick to help you thwart attempts to track you on the web.
It's a little-known built-in feature that applies to Internet Explorer 10 and later users; yes, you should update any prior versions you may still have, even if you do not use IE - many system components are using its frames.
While in Internet Explorer, press Alt-X or click the Tools button on the toolbar (most right), select "Manage Add-Ons".
Click "Tracking Protection" on the left - you will see a pre-defined "Your Personalized List" on the right.
Click the list and then click "Enable" button below.
Click "Settings" button below and select "Automatically Block" on the dialog that opens.
"OK", "Close"
Now what happens is IE will detect tracking frames on all websites that you visit.
If there are more than 10 occurences (different sites) having embedded the same tracking scripts, it will be considered a tracking network and will be blocked from placing an identifying cookies on you.
Hopefully this helps stopping the trackers "profiling" you, i.e. gathering info on types of sites you visit, and placing you into certain categories.
Possible uses of tracking involve targeted advertisement, market research for correlated traffic, audience statistics etc.
Not bad for an un-advertised feature that is given for free to all.
