How to set up a proxy server in Windows
Here's how to set up your Windows PC to use a proxy server on Windows 8 or Windows 10:
Press the Windows + I keys simultaneously to access the Windows Settings menu.
On Windows 10, click Settings > Network & Internet > Proxy. On Windows 8, click Settings > Network Proxy.
Under the Manual Setup section, set the “Use a Proxy Server” toggle to On. Make sure the “Automatically detect settings” toggle is also on.
Assuming that Windows finds a PAC file, in the Automatic Proxy Setup, set the Use Setup Script switch to On.
Enter the script address and click Save.
