Hide Recent Files from Your Jump Lists IN WINDOWS8

2. Hide Recent Files from Your Jump Lists

Top 10 Secret Features in Windows 8
Jump Lists were a great addition in Windows 7 that helped boost your 

productivity, but their "Recent Items" feature were a possible privacy 

concern—say, if there were documents or files you didn't want others to know 

you had viewed. Windows 8 lets you customize Jump Lists more than Windows 7, 

giving you the option to hide recently opened items and recently opened 

programs. To access the preferences, just right-click on the Taskbar, go to 

Properties, and click the Jump Lists tab.
