Microsoft made it harder to disable built-in Windows Defender antivirus
Since 2006, Microsoft has been actively developing its own defender antivirus software, which is built into the Windows 10 operating system by default. Until recently, users who were not satisfied with the regular antivirus software could completely disable it by editing the registry, but now Microsoft has closed this option with the release of the next update.
Despite the fact that Windows Defender provides an option with a button to disable protection in real-time, the antivirus does not completely stop working. After the release of the August update of Windows 10 4.18.2008.8 users will no longer be able to influence the defender's work in any way by editing the registry.
Microsoft has officially confirmed that the values in the DisableAntiSpyware registry entry are now ignored by the antivirus. Previously, users could set the value to 0 instead of 1, and Windows Defender stopped working after restarting the PC.
The only way to disable the antivirus after installing the current build of Windows 10 is to use third-party applications like Defender Control or Configure Defender. The functionality of the method for disabling the antivirus using the Group Policy Editor has not yet been tested.
