How to enable Network scanning in Windows Defender on Windows 10

If your Windows Defender throws up an error message saying, “Items skipped during the scan then the cause could be that you added an Exclusion to your Scan settings or if you have network scanning disabled on your system. If you face this issue, you may need need to enable Network scanning in Windows Defender on Windows 10 to resolve the problem.



The error message appears during both quick and full scans.


Enable Network scanning in Windows Defender

There are three ways to disable or enable Network scanning in Windows Defender on Windows 10. Each of these will allow network scanning.

  1. PowerShell Method

  2. Group Policy Method

  3. Registry Editor Method

Depending on the Windows version, and your privileges, you can choose one of them.


1] PowerShell Method

Launch PowerShell with admin privileges


Type and execute the command:

Set-MpPreference –DisableScanningNetworkFiles 0

There is no output for this command, so you will have to copy a file from the network and see if you still receive the error.


If you want to disable it, set it to 1.


2] Group Policy Method



Open Group Policy editor and go to:

Computer Configuration > Administrative templates > Windows components > Windows Defender Antivirus > Scan.

Double-click Scan network files and set the option to Enabled. Then click, OK.


Once you enable the setting, all network files will be scanned.


The default setting is not to scan any of the network files.


3] Registry Editor Method



If you are using Windows Home, you can try changing registry values as Group Policies are not available for you.


Open Registry Editor and navigate to:

Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows Defender

Right-click on Windows Defender and create a Key (folder) with name Scan


Under scan, create a new DWORD with name DisableScanningNetworkFiles


Set the value of the DWORD to 0 to enable scanning.


Close the Registry, next time you copy a file from the network; it will be scanned.


You can copy the key and import it into another computer to apply it instantly.

I hope the post was easy to follow and can now scan the network files.
