Manage and Disable Windows Defender Using PowerShell – TheITBros (2023)

Windows Defender Antivirus is the built-in antimalware program in Windows. Windows Defender is installed by default on all Windows operating systems to protect from viruses, worms, Trojans, and other types of malicious software. Windows Defender is productive enough and has low system requirements. It can be updated online from the Microsoft website or an internal WSUS server. This allows you to use it not only on home computers but also on SMB and enterprise networks. In this article, we will take a closer look at how to manage different settings and enable/disable Windows Defender using PowerShell.

Managing Windows Defender Using PowerShell

The main advantage of the Defender is that it is easy to use, it’s already pre-installed in Windows 10 and 11, enabled by default, and practically doesn’t need manual configuration.

Install-WindowsFeature-Name Windows-Server-Antimalware

In most cases, Windows Defender works well with the default settings, but sometimes the user needs to change its behavior. A large number of settings available from the PowerShell console: through a built-in module Defender. It appeared first time in PowerShell 4.0 and was designed specifically for Windows Defender management. This module contains 11 cmdlets, which we are reviewing today.

To display a list of cmdlets contained in the Defender module, run the following command:

To display current Windows Defender settings, you can use cmdlet Get-MpPreference. To change the settings, use the Set-MpPreference.

In the Windows Defender settings, the IPS, removable disk check, email, and some other checks are disabled by default. For example, you need to enable the scanning of removable drives. Let’s get the current settings using the command:

Get-MpPreference | fl disable*

In Windows 11 the following Windows Defender features are disabled by default:

  • DisableCatchupFullScan.
  • DisableCatchupQuickScan.
  • DisableCpuThrottleOnIdleScans.
  • DisableEmailScanning.
  • DisableRemovableDriveScanning.
  • DisableRestorePoint.
  • DisableScanningMappedNetworkDrivesForFullScan.
  • EnableFileHashComputation.
  • EnableFullScanOnBatteryPower.
  • EnableLowCpuPriority.

As you can see, scanning of removable drives is disabled (DisableRemovableDriveScanning = True). Turn it on using the following command:


Set-MpPreference -DisableRemovableDriveScanning $false

Manage and Disable Windows Defender Using PowerShell – TheITBros (8)

Also, you can disable some types of Windows Defender scanning. By defaults, Windows Defender scans the archive files (RAR, ZIP, CAB), which can potentially contain malicious files. You can disable archive files scanning using the command:

Set-MpPreference -DisableArchiveScanning $True

Manage and Disable Windows Defender Using PowerShell – TheITBros (9) .

Make sure the new setting is applied:

Get-MpPreference|select DisableArchiveScanning

Manage and Disable Windows Defender Using PowerShell – TheITBros (10)

After that, the Windows Defender will stop scanning all opened archive files in real-time.

Also, to change or remove the antivirus exclusion settings, you can use the Add-MpPreference and Remove-MpPreference cmdlets. For example, let’s add some folder paths to the antivirus exclusions:

Add-MpPreference -ExclusionPath C:\Video, C:\install

Display a list of path exceptions for Windows Defender:

Get-MpPreference | fl excl*

To exclude anti-virus scanning of certain processes, run the following command:

Set-MpPreference -ExclusionProcess "word.exe", "vmwp.exe"

To remove an exception for a specific folder:

Remove-MpPreference -ExclusionPath C:\install

Manage and Disable Windows Defender Using PowerShell – TheITBros (11)

Windows Defender has a hidden function to protect against unwanted programs (Potentially Unwanted Program — PUP, Potentially Unwanted Application — PUA). By default, it is accessible only in Windows 10/11 Enterprise edition, but with the help of the following command you can enable PUP/PUA protection in any Windows 10 edition:

Set-MpPreference -PUAProtection 1

After you turn on protection, when you try to launch or install potentially unwanted programs on your computer, you will receive the following notification from Defender in Windows 10.

Windows Defender took action

Your settings caused Windows Defender Antivirus to block an app that may potentially perform unwanted actions on your device.

Manage and Disable Windows Defender Using PowerShell – TheITBros (12)

Use PowerShell to Update Windows Defender Signatures

To start the antivirus signature update, you can use the command Update-MpSignature. By default, the Windows Defender receives updates from online Microsoft Update Servers. You can use the UpdateSource argument to specify where you want to receive the virus definition updates from.

The following virus definition sources are available:

  • MicrosoftUpdateServer;
  • MMPC Microsoft Malware Protection Center;
  • FileShares;
  • InternalDefinitionUpdateServer — internal WSUS server.

To update antivirus from a network shared folder on a Windows file server you need to download the necessary definition update files and place them into a shared network folder. Then you have to specify that Windows Defender should be updated from a file share source (use UNC path):

Set-MpPreference -SignatureDefinitionUpdateFileSharesSources \\DESKTOP-V20E3PO\Updates

To run virus update and malware definitions manually:

Update-MpSignature -UpdateSource FileSharesUpdate-MpSignature

Manage and Disable Windows Defender Using PowerShell – TheITBros (13)

In some cases, after receiving an incorrect update, Windows Defender may not work correctly. In this case, it is recommended to reset the current thread definition databases and reload them from source:

"%PROGRAMFILES%\Windows Defender\MPCMDRUN.exe" -RemoveDefinitions -All"%PROGRAMFILES%\Windows Defender\MPCMDRUN.exe" –SignatureUpdate

How to Perform Virus Scan with Microsoft Defender?

To perform an antivirus scanning of your computer, use the Start-MpScan cmdlet. With the ScanType argument, you can choose one of three scan modes:

  • FullScan — scan is performed for all files on your computer, as well as the system registry and currently running apps;
  • QuickScan — analysis of only those areas that are most likely may be infected by malware (registry, active RAM, system folders);
  • CustomScan — user selects the folders and drives to scan.

For example, run a custom scan to check the system folder “C:\Program Files”:

Start-MpScan -ScanType CustomScan -ScanPath ”C:\Program Files”

Manage and Disable Windows Defender Using PowerShell – TheITBros (14)

You can perform a full computer scan by Windows Defender using the command:

Start-MpScan -ScanType FullScan

Or quick threats scan:

Start-MpScan -ScanType QuickScan

To remove all active threat on your computer, use the command:


All Defender module cmdlets can be performed both for the local and remote computers. To connect to a remote computer, you need to use the CimSession option. For example, to get the date of the last scan from the remote computer with hostname lnd_wks21, run the following commands (WinRM must be enabled):

$session = NewCimSession -ComputerName lnd_wks21Get-MpComputerStatus -CimSession $session | fl fullscan*

You can use the Start-MpWDOScan cmdlet to perform an offline scan with Windows Defender.

After executing this command, your operating system will automatically reboot. Windows Defender will start in a special boot environment and scan your device for threats before your Windows boots.

You can check this option state using PowerShell:

You can only disable it using the Windows Security app. Go to “Virus & Threat Protection” > click “Manage Settings” > scroll down to “Tamper Protection” and move the slider to the “Off” position.
