How to Make Windows Store Work Through a Proxy
In a previous article, we discussed methods to fix Windows Store not opening. However, sometimes the Windows Store loads extremely slowly, making it nearly unusable.
Is there a way to make the Windows Store access content through a proxy? Recently, research by xiaoz found that using Shadowsocks (SS) can allow the Windows Store to work via a proxy, but it requires special configuration.

Accessing Windows Store via Proxy
When using Shadowsocks (SS), conflicts often arise between SS and the Windows Store. Once SS is set to PAC mode, the Windows Store may fail to open.
After searching online, we found the following information on GitHub:
Actually, it's not just the Windows Store that doesn't work; UWP apps in general are affected. The root cause is that the UWP sandbox environment does not connect to the local network by default. You can use loopback software to disable network protection (you can choose to disable it only for specific UWP apps), allowing them to work through a proxy.
The key to this solution is "using loopback software to disable network protection so UWP apps can use the proxy." Therefore, we need to use a tool called Fiddler Classic.
- Fiddler Classic Official Download: https://www.telerik.com/download/fiddler
- Backup Download: FiddlerSetup.exe
After installing and opening Fiddler Classic, locate WinConfig in the top-left corner.

Scroll down to find "MicroSoft Store," check the box, and save the settings.

Now, the Windows Store can access content through the SS proxy.

If you are using other proxy tools, the method and principle remain the same; you can try the steps above.
