I have installed Windows 8 Pro. Everything was going on fine, until today, Live tiles have stopped working. For example, clicking on the "Mail" app doesn't do anything. Other tiles also don't seem to do anything when clicked. Clicking on "Store" app, opens the flash screen for a sec or two, and then takes me back to the home screen.
Searched for that, and found a few links explaining the problem. They recommend to not use Avast. But, I am using AVG, in case that matters. Even after uninstalling AVG, the problem persists.
I found another post, suggesting to run the command
sfc /scannow, but that didn't fix the problem either.
