This is a very recently updated/repaired Windows 7 SP1.
As I recall, there were some issues with IE so I installed IE 10.
From the beginning, IE 10 will start, a window willl flash up and then close and that is all...
No more IE. No window. Nothing.
I have reset IE, no change.
I have tried opening with no extensions, no change.
I have unchecked the box in Programs, rebooted, rechecked the box .. etc., no change.
This appears to be a common problem but I've not found a fix that works.
