By default Windows 7 will remember your PC search queries, and display the most recent examples when searching in Windows Explorer. If you're sharing a PC and don't want everyone to see your searches, then launch GPEDIT.MSC, go to User Configuration > Administrative Templates > Windows Components > Windows Explorer, double-click "Turn off display of recent search entries..." and click Enabled > OK.
