How to proxy installed programs on the computer?

To proxy installed programs on your computer, you can configure a system-wide proxy in your operating system settings, which will route all internet traffic through a specified proxy server. For applications that do not respect system proxy settings, you can use third-party software like Proxifier or similar tools to redirect their network connections through the proxy. Ensure to set the correct proxy address and port in these tools and test the configuration to verify that the programs are successfully using the proxy. Additionally, check individual application settings as some may allow direct proxy configuration.
