PowerPoint 2013 and 2010 displays screen tips along with feature description when we hover the mouse over the menu items. By default screen tip feature is enabled in PowerPoint but if you do not want this extra information to be displayed then you can turn off using PowerPoint options.
Click File menu and then Options link
In PowerPoint Options under General tab, navigate to User Interface options.
Set the value for ScreenTip style dropdown to Don’t show ScreenTips and click OK to confirm and save the changes. This would disable the display of screen tips for all menu items in PowerPoint.
