In this tutorial we will show you how to add “Scan with Windows Defender” to the Context Menu (right-click menu) in Windows 8.1. Not like many other articles, this is the first complete guide to make you have this option not only when right-click on folders but also when right-click on any individual files.

Step 1:
Press Windows key + R to open the Run dialog box
Step 2:
Type in regedit > click OK to open the Registry Editor
(if prompted by the User Account Control, click Yes)
Step 3:
Navigate to the following key:


Step 4:
Right-click on the shell key, navigate to New, and select Key.

Step 5:
Name it WindowsDefender

Step 6:
On the right pane of the newly created WindowsDefender key, right-click then point to New > select String Value

Step 7:
Name the new string as Icon

Step 8:
Double-click on the Icon string and enter the following value > click OK

%ProgramFiles%\\Windows Defender\\EppManifest.dll

Step 9:
On the right pane of the WindowsDefender key, create another new String value. 

Name it MUIVerb

Step 10:
Double-click on the MUIVerb string and enter the following value > click OK

Scan with Windows Defender


Step 11:
Right-click the WindowsDefender key in the left pane > navigate to New > select Key

Step 12:
Name it Command

Step 13:
On the right pane of the Command key, double-click on the Default string and give it the following value:

“C:\Program Files\Windows Defender\MpCmdRun.exe” -scan -scantype 3 -SignatureUpdate -file %1


Now you can close the Registry Editor and right-click on any folder to see the option “Scan with Windows Defender” in the Context Menu.
If you get an error when trying to perform the scan, please remove the quotation marks to make it become:

C:\Program Files\Windows Defender\MpCmdRun.exe -scan -scantype 3 -SignatureUpdate -file %1


The scanning progress will be performed in a Command Prompt window and it will appear and disappear very quickly. You will only be informed and able to see the result if Windows Defender detects a thread.
The tips and tricks above works only for folders, not for individual files. If you want to see the option ““Scan with Windows Defender” when right-click on any files, you need to create the same registry keys in: 
So we create a new key named WindowsDefender

And create 2 new String named Icon and MUIVerb


Also create new key named Command under the WindowsDefender key
Now you can scan any files you want.
