Thanks for the attached screenshot. That helped me understand what you were seeing. It took quite a while experimenting with different settings to finally duplicate what was happening.
For your Taskbar settings, you have "Use small taskbar buttons" checked. Right click on the taskbar, select properties, and uncheck that box, and you will make the search box option appear. It's incompatible with the smaller taskbar height.
Glad we discovered that. Perhaps it will help others with that issue. Looks like if you want it small, you don't want the search box, or at least that's the way Microsoft saw it.
