Description of your issue, suggested solution and other information

OS: Windows 7 Ultimate

At work I am expected to use a proxy server but elsewhere (home) I turn it off.
My windows/IE proxy settings have the proxy specified but I only activate it when i'm at work:

1. Open "Configure Proxy settings" (i.e. Type "Configure Proxy settings" on windows start menu
2. Go to LAN settings
3. Check the box "Use proxy server.." and fill in something.
4. Untick the box "Use proxy server.."
5. Close OK and OK

All other applications interpret this as the proxy setting being off but youtube-dl ignores the checkbox "Use proxy server..." and uses the proxy anyway.

youtube-dl does not use these settings. Proxy is specified in your env variables.

Which env variable in windows does it use?

This is not a standard way in windows to obtain the proxy settings and therefore is, in my opinion, a bug.
All the applications I have every used depend on windows proxy settings to determine it they should use or not the proxy. Why should this be different?

Also it very rude to close an issue without debate!
