Hi Noel, yes, from what I'm reading, it's a big complex messy issue for some users.
- Aero not working, Firefox doesn't work, some sites or features don't work.
No install possible with some graphics cards... prerequisite is KB2670838, not offered by Win Update in some cases. "KB2670838 is a pre-IE 10 upgrade required for some components of DirectX for Win 7, and Windows Imaging Components."
(I don't have KB2670838 installed, and it hasn't been offered- but IE10 has. Hmm.)
Here, MS actually does offer assistance: Troubleshooting Internet Explorer 10 (IE10) Installation - Sysnative Forums "IE 10 for Win 7 - not
KB2670838 is a pre-IE 10 upgrade required for some components of DirectX for Win 7, and Windows Imaging Components. Reports are this KB is not compatible with Firefox, and some video cards.

"In the meantime, Microsoft said it’s working to resolve the issue. Affected computers come from companies including Sony, HP, Dell and Lenovo."
I'm guessing (having updated everything anyway) the PnP error is a byproduct of attempting to install IE10, and a relic of that is IE10 is shown as an installed component, which I can't uninstall.
Time to get on with other things while things settle down..
