Was using Internet explorer last night and it froze, only thing I could do was to press the reset button, it boots up got a error about a damaged registry file and recovery from backup successful and displays my wallpaper, but no icons and no taskbar, nothing happens when I press the windows key on the keyboard, mouse works but not the right click, in task manager(only thing that works) I see that explorer.exe is not running. If I try and run it I will not start.
I can reformat my machine, but if I can't find out what happened, it will probably happen again.
I use avg free v7
In case your wondering I am typing this from a laptop
