When you search through your PC from Windows Explorer, you can see the most recent searches that have been performed. If you share a PC and don’t want others to see what you’ve searched for, you can turn off the recent searches feature:
1. In the Start menu’s Search box, type GPEDIT.MSC and press Enter to launch the Group Policy Editor.
2. Go to User Configuration –> Administrative Templates –> Windows Components –> Windows Explorer.
3. Double-click “Turn off display of recent search entries in the Windows Explorer search box” and select Enabled from the screen that appears. Then click OK. The recent searches feature will now be turned off.
