Can't see explore tree

When I right click on the start button then explore there is no tree. What can it be?

 

with thw explorer window opened go to view/explorer bar /folders

 

That's a negative on that, I have that set up and I have logged in as admin. Could it be a setting in the registry?

 

not sure ,over my head if it is

 

just found this and didnot have time to read it all but it might hold some info
