Hey, I have downloaded pc me about 1 month ago on my Windows 7 a Windows 10 ISO file and installed. However, the apps do not work, such as the Microsoft Store following shows: "Check your connection" error code 0x80072EFD, Xbox live does not (supposedly no internet connection, which is not true). I hope to helpful answers. :))
The best answer
If you continue to get this error, possibly a program running on the computer application is preventing Windows Update Services (SVCHOST) on the Internet. These programs, which prevent access to the Internet, include firewalls, anti-spyware, web accelerators, Internet security or antivirus programs, and proxy servers.
