Yesterday , all things were fine and my Windows Developper Preview worked normaly without any problem.
Today, all seems to be normal but I cannot launch any
Metro style application from the start screen. I click and click again but nothing happens . The only apps that can be launched are the "not metro style" ones like Visual Studio 11, Task manager, Expression Blend ...
Is this a known issue and is there any solution avoiding to reinstall the system from scratch.
