First create an SSH connection using putty
- Open putty and select SSH and enter the address of your ssh server.

- Setup the SSH Tunnel in Putty (use whatever port you want to that is >1024)

- Name and save your putty session
Next Setup Chrome to use the ssh tunnel
- Right click on a Chrome shortcut and add the following to the Target field: "--proxy-server="socks5://localhost:1080"
Finally test the proxy
- Try the new shortcut without having putty started, and then with it connected.
