Windows 7 automatically saves all the recent searches done by the users. The last three searches become visible under the search box as you start typing in it.
There is a way in which you can disable search history display in Windows 7. But you cannot disable search history display in Windows 7 Home editions. Because you need to utilize the Group Policy Editor for this and it is not available in the Home versions.
Follow these steps to disable search history display in Windows 7.
v Enter gpedit.msc in the search box of the Start menu and press Enter.
v Goto User Configuration > Administrative Templates > Windows Components > Windows Explorer.
v Double click on Turn off display of recent search entries in the Windows Explorer search box.
v Select Enabled
v OK
