Windows Defender, also known as Microsoft Defender Antivirus is
a built-in anti-malware solution on Windows 10. It is designed
to protect your computer and connected devices from unwanted
attacks, ransomware attempts, viruses, and many other forms of
malicious rootkits used by hackers.
Windows Defender is one of the best antivirus software options
for most users. It also doesn’t slow down your system and it
downloads new definitions from Windows Update, and it even
stays out of your way.
However, there could be situations where you may want to
disable Windows Defender’s real-time protection.
Microsoft allows users to disable Windows Defender Antivirus by
editing Group Policy and Windows Registry.
To disable the Defender antivirus permanently with the
Registry, you need to create a key and name it
‘DisableAntiSpyware’ with value ‘1’.
Starting with August 2020 update (version 4.18.2007.8),
Microsoft said it has discontinued this setting and values will
be ignored on client devices.
“This setting is discontinued and will be ignored on client
devices, as of the August 2020 (version 4.18.2007.8) update to
Microsoft Defender Antivirus,” Microsoft noted in
a new update to its documentation.
While Microsoft doesn’t want you to edit the Registry to
disable Windows Defender permanently, you can still use Group
Policy editor, Windows Security app, or third-party software to
temporarily disable Defender.
By default, Windows 10 doesn’t include an option to disable the
Windows Defender permanently, but Microsoft allows third-party
anti-malware software to work alongside Windows Defender.
Windows 10’s built-in antivirus protection is automatically
disabled during the installation process of third-party
