Use SScap application. There is an Option at the bottom left corner, second icon. That's a QR Code scanner. It will automatically add the server once you captured it.
Tanong, SSCAP lang ba ang gamit mo sir? or naka proxifier ka rin??
Settings:
Right click SScap Taskbar Icon and put a check on "Enable System Proxy"
~ Go to System Wide Proxy and choose Global Mode.
~ Choose your Server.
