What is Microsoft Defender?

Microsoft Defender is a security program that helps protect your computer against viruses and other malicious software. It is designed to provide you with real-time protection against the latest threats, and to help you remove malware from your computer if it gets infected. Microsoft Defender can also help protect your privacy by blocking unwanted software from tracking your online activities.

How to disable Microsoft Defender?

1. Go to Start > Settings > Update & Security.
2. Select Windows Defender on the left-hand side, and then click the slider to turn off real-time protection.

How to re-enable Microsoft Defender?

If you’re looking to re-enable Microsoft Defender, there are a few different ways you can go about it. The first way is to simply open the settings for your antivirus program and look for an option to enable Microsoft Defender. If you don’t see this option, you can try enabling it through the Windows Security Center. To do this, open the Control Panel and go to Security Center. Under the “Security Settings” section, click on “Turn on now” next to Microsoft Defender.

If neither of these methods work, you can try manually enabling Microsoft Defender by opening the Registry Editor and navigating to the following key:

HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows Defender

Under this key, create a new DWORD value named DisableAntiSpyware and set its value to 0. Once you’ve done this, restart your computer and Microsoft Defender should be enabled.
