Did you make any changes (software installation or removal, Windows updates, etc.) just before this  happened?  What protection apps (anti-virus, anti-malware) are you using? 

Take a look at a lengthy discussion of this issue at http://social.technet.microsoft.com/Forums/windows/en-US/6f119828-dd1b-42da-b8b5-c6e6c0d5617c/no-apps-or-windows-store-work-after-upgrading-to-windows-81-enterprise?forum=w8itproinstall

And, those apps with the x on them will not work, right?

And, you did this just before this problem started??

[Nikhil Joshua]

yes

Why did you do that?  I suggest you reinstall it and see whether that resolves the problem.

Windows 8 comes with its own AV called Windows Defender. If you decide to install another AV, you will need to disable Windows Defender.

Is this the way you tried to turn on the Firewall?
