    i uninstalled windows defender from my vista business, i tried reinstalling
    it but it got the message that it's part of vista and hence i can not install
    it, tried looking for a repair but couldn't find anything.

    any ideas?

  2. How did you uninstall it?

    Have you looked into OCSetup, if it is an ospackage you should be able to
    use this to add features.

    I did the uninstall using add/remove programs

    I tried running ocsetup "defender" and ocsetup "windows defender" but no luck

    I did the exact same thing, but am not able to re-install it. I tried to
    download it again from Microsoft, but when you try to install it, it stops
    and says that because Windows if part of VISTA you do not need to download

    I had a friendly "MS Tech at India" remove it as he tried to help fix
    another problem and left it uninstalled. I would like to know how to
    re-installed it.

    Appreciate some advice....

    It did not work. There were no services with this name. I also tried Josh
    method - no luck. I downloaded the file, but Vista installer blocks it as it
    should be built. Any other ideas?

    Thanks in advance.

    I've got the same issue:

    XP Pro upgraded to Vista Business.
    Had problems with Defender.
    Uninstalled using Add/Remove Programs
    Cannot Reinstall Defender as the Setup program says "Vista has
    Defender built in, you do not need to run this" or something like
    Any ideas out there?

    Open a command prompt as administrator,
    type servises.msc
    You will see DEFENDER on the list of and select "start".

    deactivated it and stated defender was now a part of one care. But i have
    lost all the other parts of defender that one care does not provide and am

    I hate to disagree, but I was able to uninstall it using add/remove
    software, I also opened a request with tech support but for the moment
    to no avail, they suggested sfc /scannow but it didn't detect any
    problems, afterwards they asked me to regsvr32 a couple of dll's, half
    of them are missing but I didn't get any solution.

    List of dll's:
    wuapi.dll: OK
    wuaueng.dll was loaded but call failed
    wucltui.dll failed to load, module could not be found
    wups.dll: ok
    wuweb.dll failed to load, module could not be found
    atl.dll was loaded but error 0x8002801c
    softpub.dll: ok
    wintrust.dll loaded, but error 0x80070005
    initpki.dll failed to load, not found
    mssip32.dll: ok
