    To solved this follow these steps

    If you install the third party antivirus software on your windows vista then you are not able to turn on the windows defender
    So first uninstall the third party antivirus software then try to enable the windows defender
    And also check for the updates if any available
    If you find the updates then install them on your system
    • Now go to the control panel
    • Then choose the option Administrative tools
    • Now select the option service
    • Then find the windows defender and right click on it
    • Now you can select the option Automatic next to start up type
    • Then click on Apply and then click on Ok
    • Now restart the computer this will enable the Windows defender automatically when start the system
