FYI: Tried uninstalling & re-installing all CC components and re-applying the latest firmware. No change.

There's currently a bug with the BIOS that causes these tabs to disappear. Several other users have reported the same issue on their system after they updated the motherboard BIOS.

It is not because of the version of Windows.

Thanks for the info.  Would you happen to know of another thread where this issue is being tracked?
