Error code resolution when updating Windows Defender

When you try to update Microsoft Windows Defender on a Windows Vista computer, you receive an error message that resembles the following:

(Note that you need to press the F8 key before the Windows Vista progress display.) Finally, when the Advanced Boot Options menu appears, use the arrow keys to select the Safe Mode option, and then press ENTER.
