Have you ran into Windows error 0x80072EFD when opening the store? Here’s how to fix it
This error is a network error that seems to occur in the following scenarios:
1. Whenever a proxy is defined that can’t be connected to
2. When a firewall is blocking access to the outside
3. When a broken antivirus and firewall has not been stopped correctly
4. When a network adapter is configred incorrectly
As you can see above, the fix is fairly simple. Remove any firewalls, in particular COMODO and other firewalls that may not have been shut down cleanly. Re-install them properly.
Also open the network control panel and search your proxy settings (you can simply search for proxy on the taskbar)
