You might try this. Go to the main Windows Update window and

Reboot. Reboot again. Go back to Windows Update, and re-install the same
update, by clicking on the Check for Updates button.
This should essentially re-install Windows Defender on Vista.
trying this fix too but again, I don't have the file mentioned ... even did advanced search for Update for Microsoft Windows (KB931099) .. nothing ;-(
any other ways to reinstall WD ... I HOPE?
