  • Hi Midhat Zehra, 

    Did you install other antivirus software on your devices?

    The inability to turn on Windows Defender is typically the result of having a third-party anti-virus installed or failure to remove it properly (completely). Since Windows 10 Defender includes anti-virus protection, it is disabled during the installation of another anti-virus program. If a trial anti-virus (i.e. McAfee, Norton, Webroot, etc) came installed on your computer, Windows Defender will recognizes the install and disables itself when other anti-virus products are used to avoid conflicts.
