Windows Defender Items Skipped During Scan Solved

Windows 10’s built-in Windows Defender is failing to fully complete virus scans with a notification alert saying: ”Items skipped during scan – The Windows Defender Antivirus scan skipped an item due to exclusion or network scanning settings”.


This notification alert, affecting Windows 10 only, is popping up following a Windows Defender scan and, over the past few weeks, has been widely reported by a substantial number of Windows 10 users. Until very recently it was unclear exactly what was causing this issue or what the solution might be. However, a German tech writer, Günter Born, has since discovered a likely scenario and simple fix.

Fix Items Skipped During Scan

The Cause: It seems that, in earlier versions of Windows Defender, network scanning was enabled by default. However, in the latest Defender, network scanning is now disabled by default. Why Microsoft decided to make this change is anyone’s guess, but the alerts appear to merely indicate that the scanning of network files has been skipped, as it obviously would be with this option disabled by default. More MS craziness.

The Cure: The solution then is to simply enable network scanning in Windows Defender which, thankfully, is a fairly straight forward process. Strangely, in its comprehensive guide to configuring Windows Defender scan preferences, Microsoft does not recommend scanning network files, yet leaving network scanning disabled will continue displaying these notification alerts.


Personally, I would tend to leave network scanning disabled and simply ignore the notification alerts. I would also suggest utilizing a reputable third-party scanner as an alternative, at least until Microsoft fixes this silly discrepancy. I use and recommend the excellent malware scanner that’s included with the portable and free Emsisoft Emergency Kit.

That said, if these alerts are annoying you, they can quite easily be done away with. There are actually three methods to enable network scanning in Windows Defender:

  1. Via the Group Policy Editor (Windows 10 Pro only)
  2. Via editing the registry (Windows 10 Home and Pro)
  3. Via PowerShell command (Windows 10 Home and Pro)

We’re going to use the PowerShell command option because it is the simplest and applies to both Home and Pro versions. Here’s how:

  • Open a PowerShell (Admin)
  • Type or copy/paste the following command to enable scanning network files:
Set-MpPreference –DisableScanningNetworkFiles 0
  • You can confirm that this change has been made by entering the following command before and after the above command:
Get-MpPreference | findstr /i net


  • To disable scanning network files again
Set-MpPreference –DisableScanningNetworkFiles 1

NOTE: False = scanning network files is enabled. True = scanning network files is disabled.

  1. Thanks Jim,
    I have been using Emsisoft all-in-one nasty-killers full suite for many years after trying a couple of ‘freebies’ which popped up alerts wanting payment for a Pro version.
    One nasty experience with AVG free turned me off security freebies.
    I have agreed with you over many years, (Marco BB days) advocating freebies for many programmes but top-class security is foremost for me in my on-line work and client support.

    You and family keep well and safe from the current rampant virus, it would be great for a human scanner to seek and destroy it..

    Kind Regards,

    1. Hey Jonno,

      Whatever works for you mate. I do agree, there are definitely some areas where freeware doesn’t quite cut the mustard, especially where work is concerned.

      Stay safe and stay well mate,

      Cheers… Jim

  2. There were plenty of free security programs which did not keep pestering you to get their pro version, but from what I have experienced, the list is shrinking. Though it is the best way to try out a product before, if you are granted a non restricted version, there are also commercial products which offer a 30 day free trial of their fully functional unit. One such company is Kaspersky. Continue using their pro Internet Suite and am extremely satisfied. One interesting tidbit I have taken for granted which is there in the tools section, is the ability to monitor your internet traffic. Even though we might be provided with unlimited downloads, and certain providers have removed their cap limits, it is nice to see just how much we do consume daily, weekly, monthly, even yearly basics. Must remember this information is on a per computer basics. Since many people are streaming, news and movies, the internet is constantly overused and it is up to us to limit our usage, Mindblower!

  3. Hi MB,
    There were free anti-virus programmes, AVG for instance but I became way past wasting my time when more arrived on the scene, then started the ‘pop-ups for money’ annoyance, which is when I began using Emsisoft, quite a few years ago now which to me was a better option than Kaspersky..
    With anti-virus, anti-malware, and then anti-ransom was added, along with the Emergency Rescue Kit it continues to satisfy my security needs.
    Overuse of the Internet, gee whizz, we don’t need to guess who ‘overuses’ the friendly beast, especially at this time period of complete or part isolation.
