As a Windows user, you might have come across Windows Defender, the built-in antivirus software that provides real-time protection against viruses, malware, and other types of threats. While it is a useful feature for many users, some find it restrictive and might want to deactivate it.
Fortunately, you can disable Windows Defender using PowerShell, a powerful command-line tool built-in to Windows. PowerShell provides a more advanced level of control to scripted automation and administration of Windows environments. Here, we will guide you through how to disable Windows Defender in PowerShell, along with a few examples.
Method 1: Disable Windows Defender using PowerShell
Step 1: Right-click the Start menu to bring up the Quick Link menu and select Windows PowerShell (admin). This will start PowerShell with administrative privileges.
Step 2: Type the command below and press Enter to check the status of Windows Defender:
It will show you the current settings of Windows Defender.
Step 3: Type the command below and press Enter to disable Windows Defender:
Set-MpPreference -DisableRealtimeMonitoring $true
This command turns off real-time protection, which is the primary function of Windows Defender. You will receive a prompt asking if you want to continue with the operation; type Y and press Enter.
Step 4: Verify that Windows Defender is disabled by running the command below:
It should show "DisableRealtimeMonitoring : True" as the current setting.
Method 2: Disable Windows Defender using the Registry Editor
If you prefer using the Registry Editor, you can still disable Windows Defender. The procedure is almost identical to the PowerShell method, except that you navigate through the registry editor instead.
Step 1: Press the Windows key + R, then type "regedit" and press Enter.
Step 2: Navigate to the following path: HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows Defender
Step 3: If you can't find the Windows Defender key, you need to create it. Right-click on the Microsoft key, select New > Key and name it Windows Defender.
Step 4: Create a new DWORD value by right-clicking in the right pane of the registry editor and selecting New > DWORD (32-bit) Value.
Step 5: Name the new value DisableAntiSpyware and set its value data to 1.
Step 6: Restart your computer. Windows Defender should now be disabled.
Examples of Windows Defender disabling with PowerShell
Example 1: Disabling Windows Defender Real-time protection
Set-MpPreference -DisableRealtimeMonitoring $true
This command disables real-time monitoring of Windows Defender.
Example 2: Turning off cloud-based protection in Windows Defender
Set-MpPreference -DisableBlockAtFirstSeen $true
This command turns off cloud-based protection, which helps protect your computer from new and emerging malware. When you disable cloud-based protection, Windows Defender only uses the local cache to detect malware, which may reduce the effectiveness of the system.
Example 3: Removing Windows Defender
Uninstall-WindowsFeature -Name Windows-Defender
This command completely removes Windows Defender from your system.
PowerShell is a powerful tool that comes built-in to Windows, offering more advanced automation and administration of Windows environments than using the graphical user interface. You can use PowerShell to disable Windows Defender, thereby giving you more control over your computer's security preferences. However, it is important to note that disabling Windows Defender can leave your system vulnerable to threats, and should be done with caution.

PowerShell is a command-line shell and scripting language used for Windows operating systems. It is used to automate repetitive administrative tasks and manage system configurations. PowerShell provides a more powerful and flexible way to manage and automate Windows environments than using the graphical user interface.
Using PowerShell, you can perform a wide range of actions such as managing users and groups, configuring network settings, installing software, and interacting with the registry. Some of the key features of PowerShell include its ability to handle command output, input parameters, metadata, and rich objects with properties, which makes it a useful scripting tool for IT professionals.
PowerShell has built-in support for cmdlets, which are code snippets designed to perform a specific task. Cmdlets can be used as standalone scripts or as part of a larger script. PowerShell also supports the use of modules, which are sets of cmdlets that can be loaded as needed.
In summary, PowerShell is a powerful tool for Windows that allows you to automate and manage system configurations with ease.
