How to uninstall Windows Defender. Windows Defender is antimalware software and antivirus that Microsoft has integrated into the latest versions of its operating system. Supporting the same company in Redmond, this is a fairly ineffective solution that is capable of detecting only a limited number of threats. Therefore, it is advisable to replace it as soon as possible with other IT security software.
To disable Windows Defender, it is usually enough to download and install another antivirus or another antimalware.
In some cases, however, you may want to disable or even uninstall Windows Defender manually.
Disabling the program is very simple in all editions of Windows, while removing it, as it is a component of the operating system, is often complicated (and risky) -
