Hi John,
The SSU log shows there is no conflict between driver version 11 and 12. We are not able to replicate your
issue as we did not encounter the loading page issue. We use IE 11 and access Intel website and open another tab accessing another intel website, there was no mean delay.
Can you help provide the serial number of the CT desktop adatper? You can check on this website
about the location of the serial number

It is three sets of alphanumeric e.g. 00xxxxxxxxxx xxxxx xxxxxx-xxx
Thanks,
