Page Tabs are gone

Hey guys, Usually there's the row of tabs at the bottom of the program to easily change between pages.  Mine has managed to completely disappear and I'm not sure how I can get them back (i'm sure it's a check box or something, but I haven't found anything to help me find it)  I've tried resetting back to manufacturer settings, repair install, and I am still missing them. 

Thanks in advnace
