Internet Explorer and Microsoft Edge both use the Windows system proxy setting as their own preference.
Following these steps will help you set up proxy options in Internet Explorer:
- Click on the gear icon on the top right corner and select Internet options:
- The Internet options dialog will open up. Click on Connections | LAN settings to manage your proxy settings for Internet Explorer.
Remember this is a system-wide proxy setting and most programs on the system will also obey this, especially if they do not have a proxy setting of their own.
