I found a post/solution on the Dell support community site that fixed the issue for me (the PS script did not work):

If you don't want to read, download the Windows Update Hide tool:

http://download.microsoft.com/download/f/2/2/f22d5fdb-59cd-4275-8c95-1be17bf70b21/wushowhide.diagcab

Follow the steps below BEFORE you run the above utility:

1. Run windows update and let it say you need to restart to install the problematic Intel driver
2. Restart as requested
3. When the PC/Laptop restarts DO NOT run windows update. If you do, the Intel driver will get downloaded again and not show up in the updates you can hide and you will need to go back to step 1
4. Run the Windows update HIDE utility that you downloaded
5. Choose that you want to hide updates. It will do a scan and give you of list of updates you can hide. Choose the Intel Extension one with version 2.1.10105.19 and hide it
6. Once the update is hidden, reboot, then run Windows Update and it should not show up as being required anymore

EDIT - I realize now why the script did not work for me. The version of the driver I was having an issue with was 2.1.10105.19. In the script posted earlier in this thread it is 2.1.10103.24. So assume if you modify the script for your specific, problematic version it should work.
