How to force ALL traffic to go through the local proxy?

Question

Windows

There is a HandyCache locale. It is necessary to make sure that ALL PC traffic goes through it. For example, installed programs like spotify / telegram flatly refuse to use a local proxy, although it is directly registered in Windows.

Answer 1

Raise the VPN, set up the connection and all traffic will go through it. There already routing to make a transparent proxy. And all sorts of SOCKS and HTTP is if the program itself can.
