    Hello friend.......

    If you have AVG,McAfee,Norton,Microsoft security essentials etc installed they will have either have a conflict with windows defender or disable.....

    Microsoft security essentials has its own built in version of defender and should automatically disables vista's version of windows defender.....

    If it doesn't
    'http://windows.microsoft.com/en-us/w...nder-on-or-off'

    turn windows defender on or off information at the above microsoft link...

    Hope the above explains common compatability problems with windows defender....

    If you install any of antivirus softwares on your system then there may be a conflict occurs betwwen Windows Defender and the installed Anti virus software
    Then the Windows defender turn off by it self
    If you want to turn on the Windows defender you need to uninstall the antivirus software and also run the System file checker tool once to fix the errors if any

    To run the SFC follow these steps


    • Press windows+Q to open the charms bar
    • Then type cmd in the search box
    • Then select the cmd and then right click on the cmd
    • Then choose the option Run as Administator
    • Now type sfc/scannow in the command prompt
    • Then press enter
    • Now the SFC fix the errors if any

    After this you can enable the windows Defender with out any problem
