微软商店（Microsoft Store）的 Code: 0x80072EE7 Check Your Connection问题，和Edge的Can't Reach this page的问题。网上找了很多方法都不好使。什么sfc，Powershell什么的，都没用。

还是在知乎上发现了一个解决办法。

Hello,

Thank you for contacting us.

Unfortunately, Microsoft has completely broken backward compatibility for Metro subsystem so it will take some time to add Metro support to Proxifier.

>> I run the proxifier,it works well on the desktop,but the metro apps are all cannot connect to the internet
>>

This is a known problem. At the moment I can offer you the following workaround.

1.
In the system registry go to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\WinSock2\Parameters\NameSpace_Catalog5\Catalog_Entries
Search through numeric child entries like 000000000001, etc and find one that has Enabled parameter = 0.
It should also has LibraryPath=%SystemRoot%\System32\mswsock.dll
Change Enable parameter to 1.

在系统注册表里进入到KEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\WinSock2\Parameters\NameSpace_Catalog5\Catalog_Entries，在该项目下找到类似 000000000001这样的项目栏（比如我的就是000000000005中），在其中找到一个该项含有LibraryPath=%SystemRoot%\System32\mswsock.dll这样一个项目栏，将里面的Enable项的值改为1。

2.
Do the same for HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\WinSock2\Parameters\NameSpace_Catalog5\Catalog_Entries64.
(64-bit Windows only).

如果你安装的是64位系统，那么你还需要在HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\WinSock2\Parameters\NameSpace_Catalog5\Catalog_Entries64中做上述同样的事情。（仅限于64位系统，32位没有该项）

3.
Reboot your computer. Proxifier will warn you that Winsock settings are incorrect. Ignore this message - click "No".

After that Metro (Windows Store) apps should work fine. Although they will still bypass Proxifier.

If you are going to test this, please let me know whether this fix works properly for you. Are there any side-effects for Desktop (normal) applications running with Proxifier.
I will really appreciate your feedback.

Thanks,
Sergey,

经过测试，把注册表里两个Enable改成1之后，马上就能上网了。
