MAKE SIMPLE PC PROXY APPLICATION

HI, I would like a simple proxy application which can run on all windows versions. When activate it, it will automatically tick box "Use Proxy Server for your Lan" in Lan Settings Here is details of how my application will work: 1. Proxy app won't need to install to run. It will run with windows startup 2. Left click it's icon to activate/inactivate the application. Right click to Change proxy server | Quit (Note: When run with windows startup, this app will connect to my linux server to download a text file which contains proxy server detail and save in it's own memory. Here is the format: - IP:Port Username:password - IP:Port Username:password ....) 3. When a proxy server is taking longer than usual to connect to the internet, the application will auto change to another proxy server. 4. When proxy server needs username and password to login, the application will auto fill this
