I can't type in the Search Box. If I change it to a "Search Icon", I can click on it but nothing happens. In task manager, I see that SEARCHUI.EXE is running - I've closed it, watched it re-load itself, but same results, can't type in the Search Box. Also, on another related note, Cortana doesn't open for me, even Cortana Settings. If I click on Cortana settings, nothing happens. I've already tried sfc /scannow, it never finds any corrupted files. I've installed all Windows updates up to the time of this post.
