How to get the boot camp icon into the Windows tray?

Hi Folks,

I have installed Windows 10 on two macs and in both cases the Boot Camp icon for the Windows tray is absent. Also, using search lite on the mac I find no Boot Camp files. Both machines are Mac pros, one New one Old.

I can still do the Alt key thing and choose, but I can't set Boot Camp preferences.

Any suggestions?

TIA,

Shane
