Enable Loopback Utility

Enable Loopback Utility by Eric Lawrence is a small, purpose-built tool that lets Windows Store and UWP apps connect to localhost. By default, modern Windows apps run in an AppContainer that blocks loopback (connections to 127.0.0.1), which can break local testing, debugging, and proxy scenarios. This utility provides a simple interface to grant or revoke loopback exemptions per app, making it easy to test with local web servers, APIs, and debugging proxies like Fiddler.

Key features:

• Enumerates installed Store/UWP apps with friendly names and package identifiers
• Enables or disables loopback exemptions per app with a click
• Applies changes instantly and can restore defaults at any time
• Complements the CheckNetIsolation command by offering an easier UI
• Affects only Store/UWP apps; traditional desktop apps are unaffected

Requirements:

• Windows 8 or later (including Windows 10/11)
• Administrator privileges to apply exemptions

Ideal for developers, testers, and IT professionals who need reliable local debugging without altering app code or network configuration.
