Ever since Microsoft released Windows Vista, the Redmond giant has made it possible for users to disable Microsoft Defender by way of the Registry.
Unfortunately, by granting that ability, it gave well-designed malware strains the ability to do the same.
That is now changing.
As the company explains in a recent blog post:
"DisableAntiSpyware is intended to be used by OEMs and IT Pros to disable Microsoft Defender Antivirus and deploy another antivirus product during deployment. This is a legacy setting that is no longer necessary as Microsoft Defender antivirus automatically turns itself off when it detects another antivirus program.
This setting is not intended for consumer devices, and we've decided to remove this registry key. This change is included with Microsoft Defender Antimalware platform versions 4.18.2007.8 and higher KB 4052623. Enterprise E3 and E5 editions will be released at a future date.
