Many Win10 users will encounter 80072ee7 (or 0x80072ee7) errors when opening the app store or update. This error is generally caused by the inability to connect to the Microsoft server. There are many reasons for this problem, such as campus and corporate intranet firewall blocking, proxy server issues, DNS issues, and native security software blocking.
After this problem, you can try to replace other valid DNS servers. The effective server can use the public DNS service launched by Tencent. You can consider turning off the local security software and firewall. You can also check whether the Hosts file is valid, the specific method is as follows:
1, enter C:\\Windows\\System32\\drivers\\etc, as shown below -
2 Right click on the hosts file, select the first item "Open with", then select "Notepad", click "OK", as shown below -
3, view the items after opening If there is no "#" in front of the project related to Microsoft Windows update, you need to add it manually, or delete the project directly
4, save it after saving it
If you are in trouble, you can also use the soft media Rubik's setting master to "repair" the Hosts file. You can open the file in Setup Master → System Security → Hosts File Management, or you can click the “New” button to create a Host directly. The effect is the same as that created in the Hosts file, but it is more convenient. Similarly, you can delete and edit Host.
