Want to get rid of the mostly useless Windows Defender security tool from your Vista computer? Ha! Microsoft tricked you! You won’t find Defender in the Programs and Features control panel because you can’t uninstall the tool, at least not without serious (and unnecessary) headaches. Deleting the Defender executables can cause your computer to throw out error messages, so actually removing the code from your machine is not advised.
