How to Disable Windows Defender Permanently or Temporarily

Windows Defender is an antimalware software built into Windows 10 and designed to protect your computer from viruses, rootkits, ransomware, spyware, and other malware forms. Based on various tests carried out by leading IT and security experts, Windows Defender is rightfully among the best free antivirus. While this is one of the best antivirus solutions, some users may decide to disable Windows Defender temporarily or permanently.

For example, it is necessary to disable Windows Defender temporarily when you have to perform a specific operation that conflicts with the antivirus. You can also permanently disable Windows Defender if you are configuring a kiosk computer that will not connect to the network and therefore will have no problems safety.

Before continuing, it is important to specify that Windows 10 does not allow you to permanently uninstall or stop Windows Defender unless you install a third-party solution. In that case, Microsoft’s antivirus software will automatically disable itself. However, it is easier to disable Windows Defender with several procedures that I will show you in the next paragraphs.

How to disable Windows Defender

Before disabling Windows Defender, make sure that you are perfectly sure of the operation you are about to perform and that the software you are using is 100% safe.
