Allow Windows Store and Metro Apps through firewall

Hi. I need help regarding a particular matter.

I am having some issues with the Windows 8.1 Store app.
It says that I am not connected to the internet (which I am).
I have taken other troubleshooting steps such as sfc /scannow,
DISM Tool. I have a direct connection (no proxy) to the internet,
but still I cannot connect.

What I want to do is to force “allow” for windows metro apps,
windows store and anything related to it, to access the internet
(create an explicit allow connection though Comodo Firewall)
to see if this works… just in case

Problem is, I don’t know how :smiley:

So I would kindly ask someone to help me, if he/she knows
how to do that. Thank you in advance.
