Dear Wasim
Thank you very much for taking the trouble to analyse the dump files. I am afraid that your conclusion doesn't surprise me as this is documented in KB2670838.
Here is an extract relating to the documented 'Incompatibility issues with certain computers that have hybrid video cards' which identifies my device as having no compatible drivers:

Note For computers that are marked as "None" in the latest compatible drivers, Microsoft is currently working with AMD to find the cause of the problem and determine the appropriate fix. If you have installed the platform update for Windows
7 on this computer and you experience the incompatibility issue, we recommend that you uninstall update 2670838 temporarily.
To uninstall update 2670838, follow these steps:

The reason I have started this thread is that IE11 was pushed to my laptop by Windows Update along with the other updates which presumably were intended to fix the issue. This combination of 'fixes' clearly does not work on my Sony VPCCB2C5E.
I do not believe there is a solution to the issue by uninstalling the Intel driver and reinstalling a 'native' version owing to the hybrid configuration. If this was the case, I am sure someone would have documented it before now - this issue has been
running since IE10 was released after all.
The further frustration is that it is not clear who 'owns' this issue and what if anything they are doing about it. KB2670838 suggest that Microsoft is working with AMD to resolve it but my experience of applying the recent updates is that further
work is required.
Could I ask you please to forward this issue to whoever is responsible in Microsoft and if possible report back here on whether there is likely to be a resolution? It appears to me that Microsoft, AMD and Sony have just abandoned the problem (and their
customers). It would also be helpful if Windows Update did not push incompatible updates.
What do you recommend as the most elegant method of reversing to the stable configuration with IE9 - system restore or uninstalling the updates by the way?
Kind regards
