Microsoft Defender is a powerful antivirus and antimalware software that comes pre-installed on Windows 10 devices. It offers real-time protection, cloud-based scanning and automatic updates to keep your system safe from various threats. However, some users may want to customize Microsoft Defender settings to suit their preferences and needs. In this blog post, we’ll show you how to adjust Microsoft Defender to achieve a “zero tolerance” level of security, as well as some other useful tips and tricks.
What is the “zero tolerance” safety level?
The “zero tolerance” security level is a term that refers to the highest possible level of protection that Microsoft Defender can provide. It means that Microsoft Defender will block or quarantine any file or program that it detects as potentially unwanted or malicious, even if it has a low or medium severity rating. This can help prevent any infection or compromise of your system, but it also presents some drawbacks. For example, you may encounter more false positives, which means that some legitimate files or programs may be blocked or quarantined by mistake. You may also experience some performance issues, as Microsoft Defender will scan more files and use more resources.
How to enable the “zero tolerance” security level?
To enable the “zero tolerance” security level, you must modify the Microsoft Defender registry settings. This is an advanced procedure that requires administrative privileges and caution, as any error can cause serious problems to your system. Therefore, we recommend that you back up your registry and create a system restore point before proceeding. Here are the steps to follow:
Open the Start menu and type “regedit” (without quotation marks) in the search box. Right-click on the Registry Editor application and select “Run as administrator”.
2. In the Registry Editor window, navigate to the following key: HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows Defender
3. Right-click on the Windows Defender key and select “New” > “Key”. Name the new key “MpEngine” (without quotes).
4. Right-click on the MpEngine key and select “New” > “DWORD Value (32-bit)”. Name the new value “MpEnablePus” (without quotes).
5. Double click on the MpEnablePus value and change its data from 0 to 1. Click “OK” to save the changes.
6. Close the Registry Editor and restart your computer for the changes to take effect.
You have now enabled the “zero tolerance” security level for Microsoft Defender. To disable it, simply change the MpEnablePus value data to 0 and restart your computer.
What are some other tips and tricks for Microsoft Defender?
In addition to tuning Microsoft Defender to achieve a “zero tolerance” level of security, there are other tips and tricks you can use to improve its performance and functionality. Here are some of them:
