The trick I am going to share will add a “Scan with Windows Defender” option to the context menu that appears when you right-click a folder. It works similarly to the “Scan with Microsoft Security Essentials” option on previous versions of Windows.
1-Download the .zip file provided at last.
2-Extract it and run AddWindowsDefenderToContextMenu.reg file it contains.
4-It also contains a file RemoveWindowsDefenderToContextMenu.reg
Note-Do it on your own risk.Although I checked it and its working.
