Windows Defender is skipping files on Windows 10, but there’s a fix


All Windows 10 computers come pre-loaded with Windows Defender,
which is set to be renamed to Microsoft Defender, is on par
with third-party security products. It’s no surprise that many
consumers use Windows Defender on their Windows 10 for security
and malware security.

Windows 10 and Windows Defender are updated regularly to
protect your computer from malware and attackers. However, a
recent update for Windows Defender has gone wrong and Windows
10’s built-in antivirus protection software has been skipping
files during automatic and manual screens.

As we
reported recently, Windows Defender’s automatic, quick and
full scans skip certain files and the error message is then
displayed via notification in the Action Center.

Windows Defender scan skipped

The error message states that some items were skipped due to
the exclusion or network scanning settings. Unfortunately, it’s
unclear how many items were skipped during the scan and there
is a possibility that this is a false error.

It appears that the Redmond firm recently implemented a change
that blocks Windows Defender from scanning network files.
Previously, network scanning was enabled by default, but the
March update has disabled it, which is resulting in the error

Those who are reporting this problem say they don’t have any
exclusions applied, which suggests that the behaviour was
quietly implemented in an update.

While that’s not much of an explanation, those who are
reporting this problem should consider ignoring the error as it
is most likely to be false.

As some users have observed, you can manually turn on network
scan and Windows Defender will no longer display the warning in
Action Center.

It is worth noting that Microsoft says it does not recommend
users to manually enable this option and scan for
files. In our opinion, you should not meddle with network
scanning settings and ignore the warning as Microsoft might
update Defender to remove the error message in future.

If the error is bothering you, we have an unofficial

How to fix Windows Defender items skipped during scan error

First and foremost, run the ‘Get-MpPreference’ command in
PowerShell on Windows 10. If DisableScanningNetworkFiles is set
to ‘True’, network scanning is disabled and Windows Defender
may report the above error.


To fix ‘items skipped during scan’ error in Windows Defender,
enable network scanning with the following elevated PowerShell

  • Set-MpPreference –DisableScanningNetworkFiles 0

After the changes are applied, restart your system and this
will resolve Windows Defender’s problem.

Again, as we noted above, users should ignore the warning and
don’t tamper with PowerShell.
