Rimuovere barra laterale e home da adobe reader DC

Go to the install directory, i.e. C:\Program Files (x86)\Adobe\Acrobat Reader DC\Reader\AcroApp\ENU
Create a new subfolder (I used Disabled).
Move three files from the ENU folder into the new Disabled folder: AppCenter_R.aapp, Home.aapp and Viewer.aapp.
Open a PDF and no more Tool Pane!
