Your IP is hidden when using Tor properly. The IP of the exit node is revealed to the site. Get the Tails OS. It's lightweight and easy to use. There is a windows tor browser bundle, but it is not nearly as idiot proof as Tails. https://tails.boum.org/
Do u think the windows tor browser bundle does not hide IP properly ? I was also reading about TOR bridges. Are they really required to be used ? I'm not into any illegal activity. But I dont want to attach site cookies with my IP or reveal my Public IP to every site owner. Does not simple windows tor browser bundle serve this purpose ?
