Focus control in Windows 8

Hi,

 

I recently bought a bunch of stardock software and thought I'd throw in windows FX 5.1 as I love the look of the focus feature for background windows. I'd seen the software was now compatible to work on windows 8 so all was good.

I installed it recently and cannot find the option for it anywhere. Can anyone help me?? How do I make the background blur?

 

Thanks in advance.
