5. How to turn off Windows Security in Windows 10 (new version)

Note:

Windows Defender AV and the Windows Security application use similarly named services for specific purposes.

The Windows Security application uses the Windows Security Service (SecurityHealthService or Windows Security Health Service), which then uses the Security Center (wscsvc) service to ensure the application provides the most up-to-date information about the protection status on the endpoint, including includes protection provided by third-party antivirus products, Windows Defender Firewall, third-party firewalls, and other security measures.

These services do not affect the state of Windows Defender AV. Disabling or modifying these services will not disable Windows Defender AV and will result in a lower protection status on the endpoint, even if you are using a third-party antivirus product.

Windows Defender AV will be automatically disabled when third-party antivirus products are installed and updated.

Disabling the Windows Security Center service will not turn off Windows Defender AV or Windows Defender Firewall.

(Service Windows Defender Security Center)

HKEY_LOCAL_MACHINESYSTEMCurrentControlSetServicesSecurityHealthService

(Service Security Center)

HKEY_LOCAL_MACHINESYSTEMCurrentControlSetServiceswscsvc

DWORD Start

2 = On (Activate)

Overall, there are many outstanding antivirus software that are worthy alternatives to Microsoft Defender Antivirus. However, Windows 10's integrated antivirus is still considered one of the best virus browsers for current Windows 10 users.

Why disable Windows Defender (Windows Security) on Windows 10?

Typically, this antivirus will prevent the installation of software from a little-known developer, because it rates that program as suspicious. Anyone who uses legitimate third-party apps will find this annoying. For example, it can be frustrating when custom software that you're using for work and that certainly doesn't pose a threat to your system is constantly being warned by the built-in antivirus software.

You may have other reasons to disable Windows Defender temporarily or permanently, although Windows Defender offers one of the best antivirus solutions for Microsoft operating systems. For example, the program may consume too much of the system resources of a low-end PC.

If your device is not at risk of malware exposure, you can turn off Microsoft Defender Antivirus. However, be very cautious before making a decision and always have additional anti-malware program available (one of the suggestions that the article gave above). The article strongly recommends that you do so to keep your computer protected.

You might not need Windows Defender because you're using another developer's antivirus solution. That's not unusual, as these programs will often perform better than the original Microsoft program.

Some frequently asked questions

1. Is it safe to permanently disable Windows Defender?

The answer is yes. However, you should immediately activate another anti-virus program. Windows Defender is designed to protect you from the moment you start using Windows, but you don't have to use it if you don't want to. That's why you should leave Windows Defender running until you're ready to install something else.

Even if you are extremely careful, chances are you will encounter a virus at some point. Blocking viruses is much easier than trying to remove them.

2. Does Windows Defender make your PC run slower?

Unless you're performing a full system scan, you won't notice any real noticeable performance hit. In fact, Windows Defender uses less system resources than most other antivirus applications. If your PC is running slow, check Task Manager to see what's running and using the most resources. It could actually be a sign of a virus infection that has bypassed Windows Defender or another antivirus application you have installed.

3. Does installing another antivirus application disable Windows Defender?

This is partly true. Windows Defender can still perform periodic scans and will receive regular updates. However, Windows defaults to giving priority to the antivirus program you have chosen. For example, when you install Malwarebytes, Windows automatically turns off real-time protection in Windows Defender but keeps periodic scanning enabled.

If you want to disable Windows Defender, you will need to perform the options above.

4. Is it safe to run Windows Defender with another antivirus application?

Have. The two programs rarely interfere with each other. Just make sure you don't both try to run the scan at the same time, as this will hurt your PC's performance. Think of Windows Defender as backup antivirus software. However, disabling it won't do any harm. Feel free to use the anti-virus software you want.

Good luck!
