  • Uninstall the trial versions of the other AV tools.

    Download and run this tool:

    and "take ownership" of the following key:

    HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows Defender

    Now change the values DisableAntiSpyware and DisableAntiAntiVirus from 1 to 0.

    Now Defender will be started again.

  • You just have to uninstall your current Anti-Virus program and then restart your PC and Windows Defender will enable or you could enable it by open it and turn it on.
