New W10 build, all updates. Suddenly noticed taskbar icons in notification area are gone. I know how to selectively place them, so I went into settings to see what happened. I went to "Select which icons appear on taskbar", and the page was completely blank. There was nothing for me to select. I ran system file checker, checkdisk, and the DISM,Restorehealth command, with no change. I've searched Google for this as well. Any ideas?

Running programs, do appear on taskbar, as they should, as do date and time.
