I disabled the sanbox entirely (by right clicking the taskbar icon and by going to Defense+ settings), then I reboot the PC, ran CLT again, and gave me almost the same score (+10 points).

I also followed the instructions for configuring CIS in this post

Now I'm worried about my computer security with such a low score. Any other ideas?
