Hi Ken
If you do not have those options, you are running an older version of Windows 10
If your system is stuck in a High contrast Theme, then that will have disabled the Transparency in Windows 10
On the High Contrast setting page, is the button to turn that off not enabled?
Possibly upgrading your system to the latest version of Windows 10 would resolve all this for you . . .
Click the link below, then click 'Update Now' on that page to immediately get 1903 and bring your PC right up to date
