微軟商店（Microsoft Store）的 Code: 0x80072EE7 Check Your Connection問題，和Edge的Can't Reach this page的問題。網上找了很多方法都不好使。什么sfc，Powershell什么的，都沒用。
還是在知乎上發現了一個解決辦法。

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.在系統注冊表里進入到KEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\WinSock2\Parameters\NameSpace_Catalog5\Catalog_Entries，在該項目下找到類似 000000000001這樣的項目欄（比如我的就是000000000005中），在其中找到一個該項含有LibraryPath=%SystemRoot%\System32\mswsock.dll這樣一個項目欄，將里面的Enable項的值改為1。
2.
Do the same for HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\WinSock2\Parameters\NameSpace_Catalog5\Catalog_Entries64.
(64-bit Windows only).
如果你安裝的是64位系統，那么你還需要在HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\WinSock2\Parameters\NameSpace_Catalog5\Catalog_Entries64中做上述同樣的事情。（僅限於64位系統，32位沒有該項）
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,

經過測試，把注冊表里兩個Enable改成1之后，馬上就能上網了。
