So I think it's time I acted smart and got onto tails. Obviously it's a much more secure OS etc, but if I've already used tor on my Windows machine, this seems pointless. How should I go about destroying any trails my windows OS has left? I want to do this before I start using tails as there's no point in using tails if there's still traces on my HDD from my windows install.
Tumble all your funds, to a new Electrum wallet on tails. All your passwords and usernames are dead. Make new ones. Make sure your scripts are always turned off...
