    How to reinstall Defender

    Vista Home Premium. I uninstalled Windows Defender and now cannot reinstall
    it as the installer says "Vista already includes Defender"

    I have Vista Home Premium and did the same thing. I still have not figured
    out how to reinstall or activate what is left on my computer. I still have
    the Windows Defender files on my C: Drive but cannot open them. I deactivated
    them someway. I recieved the same error message when trying to reinstall. I
    also cannot delete what is left in my system.

    RE: How to reinstall Defender

    Hi you can reinstall defender by using the restore option on your computer by
    going through the start menu and accessories to system tools and restore. You
    will see many restore points and the defender uninstall will show up. just
    restore to the point before the uninstall. I did this and defender came back
    and is working perfectly.
    I hope this helps everyone. Eileen

    I also would like to know how you uninstalled Defender because I'm trying to
    do that now and I can't seem to find a way to do it.

    You can't uninstall Defender. It can be turned off, but non uninstalled.

    Re: How to reinstall Defender


    Hi all I too had the same problem with uninstalling my beta version of
    defender after upgrading from xp to vista and after lengthy searching I
    think Ive finally found a fix. Please read and follow the following
    carefully.The root cause of 0x8007006 is similar as 0x8007002. It can
    be caused by damaged registry information or Windows Defend files.




    Step 1: Back up Registry

    ==================

    1. Click Start, type "regedit" (without quotation marks) in the search
    bar and press Enter.

    2. In the Registry Editor, click File menu, and click Export.

    3. In the Save In list, select the folder where you want to save the
    backup.

    4. In the File Name box, and type a name for your backup file, such as
    "Options" or "Backup".

    5. Click Save.



    Step 2: Create and Run the Registry File

    ==================

    1. Click Start, type "notepad C:\register.reg" (without quotation
    marks) in the Search bar, and then click OK. Choose Yes when you are
    prompted to create a new file.

    2. Copy the following texts between the star marks and then paste them
    into the opened Notepad window:

    Re: How to reinstall Defender


    Hi all. What happened with me was that I didn't uninstall my beta
    version prior to upgrading to vista premium and then after I upgraded
    the beta version was still showing up in the "uninstall or change
    programs list". When I "uninstalled it" it removed the beta version
    but took some essential files with it from the windows vista version of
    defender. You have to uninstall it before fixing the windows vista
    version of defender. After which time You can begin the fix process
    which I've already explained(above, in previous message).
    [B]Note: The windows vista version of defender does not and is not
    supposed to show up on your "change or uninstall programs list". If
    you have one showing there then its the beta version. Hope this
    helps!!B]

    Just wanted to let you know the fix posted by Cdn ninja worked for me
    and I am not a advanced computer user. I had upgraded from xp to vista
    using a Dell upgrade disk and developed the defender problem. Following
    the cdn ninja instructions corrected the problem.
